However\, when pursuing higher en ergy and finer physics in the PWFA problems\, a code that can cost less co mputing resources is required. Therefore\, we apply the azimuthal decompos ition method in the quasi-static PIC algorithm and develop a new code. The code is based on the open source 3D quasi-static PIC code QuickPIC\, and it is called QPAD that stands for QuickPic with Azimuthal Decompostion. In this work\, we present the basic algorithm in QPAD and some comparisons b etween QPAD\, QuickPIC and a fully 3D PIC code OSIRIS.\n\nhttps://indico.i np.nsk.su/event/42/contributions/2167/ LOCATION:Budker INP URL:https://indico.inp.nsk.su/event/42/contributions/2167/ END:VEVENT BEGIN:VEVENT SUMMARY:Innovative accelerator techniques in Novosibirsk DTSTART;VALUE=DATE-TIME:20210317T061500Z DTEND;VALUE=DATE-TIME:20210317T063500Z DTSTAMP;VALUE=DATE-TIME:20260307T091801Z UID:indico-contribution-42-2166@indico.inp.nsk.su DESCRIPTION:Speakers: Konstantin Lotov (Budker INP)\nWe review the activit y of four research groups:\n- theoretical group that develops a quasi-stat ic code LCODE for simulations of plasma wakefield acceleration and makes n umerical and theoretical studies of plasma based accelerators\;\n- theoret ical group that studies collective relaxation of electron beams and THz ra diation from plasmas\;\n- group that develops novel W-band accelerating st ructures\;\n- experimental group that prepares laser-plasma experiments wi th a two channel multiterawatt laser system based on OPCPA.\n\nhttps://in dico.inp.nsk.su/event/42/contributions/2166/ LOCATION:Budker INP URL:https://indico.inp.nsk.su/event/42/contributions/2166/ END:VEVENT BEGIN:VEVENT SUMMARY:Advanced accelerator R&D activities at PAL DTSTART;VALUE=DATE-TIME:20210316T070000Z DTEND;VALUE=DATE-TIME:20210316T072000Z DTSTAMP;VALUE=DATE-TIME:20260307T091801Z UID:indico-contribution-42-2165@indico.inp.nsk.su DESCRIPTION:Speakers: Inhyuk Nam (Pohang Accelerator Laboratory)\nLaser-pl asma accelerators have been the most promising candidates for future compa ct accelerators which can be used for next-generation free-electron lasers (FELs). However\, their poor stability and reproducibility limit the appl ications of the laser-plasma accelerator. PAL-ITF (injector test facility) has an S-band RF photocathode gun and final energy of 70 MeV\, with a lo wer emittance\, which can be used for the seed beam for advanced plasma ac celerators. The electron beam from the RF photocathode gun should be match ed with the wakefield focusing strength for the beta motion of the electro n beam inside the wakefield for the external injection scheme. Therefore\, the electron beam size should be decreased at the entrance of the plasma source for good matching\, and for preserving the emittance\, slowly incre asing the plasma ramp is also required. We currently have been prepared th e plasma lens experiments for focusing on the electron beam using the disc harge capillary plasma source. We also developed the capillary source with a long ramp plasma for emittance matching. In this presentation\, we pres ent on-going advanced accelerators R&D plans at PAL-ITF.\n\nhttps://indico .inp.nsk.su/event/42/contributions/2165/ LOCATION:Budker INP URL:https://indico.inp.nsk.su/event/42/contributions/2165/ END:VEVENT BEGIN:VEVENT SUMMARY:Diagnostics of the proton beam position using the luminescence of the lithium neutron producing target DTSTART;VALUE=DATE-TIME:20210317T060000Z DTEND;VALUE=DATE-TIME:20210317T063000Z DTSTAMP;VALUE=DATE-TIME:20260307T091801Z UID:indico-contribution-42-2096@indico.inp.nsk.su DESCRIPTION:Speakers: Evgeniia Sokolova (BINP)\nIn the Budker Institute of Nuclear Physics an accelerator based epithermal neutron source was propos ed and designed [1] to the development of the perspective cancer treatment \, which is the Boron Neutron Capture Therapy. The principal unit of the f acility is the neutron producing target. The target was irradiated by the proton beam with various energy values from dozens of keV to 2 MeV. Moreov er\, the current of the proton beam was gradually changed from dozens of µm to 2.5 mA. With the proton beam hitting the target surface the lumines cence was detected. The luminescence was visually seen with the use of Sma rt IP-camera (Hikvision\, China)\, mounted on the BaF2 window. The observe d wavelengths were measured using spectrometers (HR2000+ (Ocean Optics\, U K)\, CCS100 Compact Spectrometer (Thorlabs\, USA)). The spectrum measureme nt was carried out through the window with the fused quartz glass. The dis tinctly distinguished spectral lines of lithium (670.67 nm and 610.4 nm) w ere detected. Furthermore\, hydrogen lines were detected\, which correspon d to the proton beam presence\, and lines suspected to be caused by an arg on presence. \nIt is very important to be sure that the proton beam is on the target during the experiments. The luminescence allows online watching for the proton beam footprint on the target in the process of neutron gen eration. In this way\, it helps to control the location of the proton beam . \nAcknowledgments\nThe reported study was funded by RFBR\, project numbe r 19-32-90119.\nReferences\n1. S.Yu. Taskaev.

CSNS is designed to accele rate proton beam pulses to 1.6 GeV kinetic energy\, striking a solid metal target to produce spallation neutrons. CSNS has two major accelerator sys tems\, a linear accelerator (80 MeV Linac) and a 1.6 GeV rapid cycling syn chrotron (RCS). The RCS accumulates and accelerates the proton beam to 1.6 GeV and then extracts the beam to the target at the repetition rate of 25 Hz. The Beam commissioning of CSNS/RCS had been started since April 2017. At the end of February 2020\, CSNS reached the design beam power of 100-k W with very low uncontrolled beam loss. The most important issue in high-i ntensity beam commissioning is the beam loss control\, as well as the cont rol of induced activities\, to meet the requirement of manual maintenance. The beam intensities attainable in CSNS/RCS are mainly limited by beam lo ss induced by collective effects\, e.g. space-charge forces\, beam instabi lities\, and stripping foil scattering. A series of solutions were propose d to mitigate collective effects. After the beam loss optimization\, a 100 -kW beam operation with very low uncontrolled beam loss was established at the end of February 2020.\n\nhttps://indico.inp.nsk.su/event/42/contribut ions/2099/ LOCATION:Budker INP URL:https://indico.inp.nsk.su/event/42/contributions/2099/ END:VEVENT BEGIN:VEVENT SUMMARY:Experiments at electron-positron colliders at BINP DTSTART;VALUE=DATE-TIME:20210316T033000Z DTEND;VALUE=DATE-TIME:20210316T040000Z DTSTAMP;VALUE=DATE-TIME:20260307T091801Z UID:indico-contribution-42-2163@indico.inp.nsk.su DESCRIPTION:Speakers: Pavel Logatchov ()\nStatus and results of experiment s CMD-3 and SND at VEPP-2000 collider and KEDR at VEPP-4M collider at BINP will be presented.

After a century of studies\, it is only recently that sufficiently high electromagnetic field strengths ha ve been available to experimentally study the nonlinear regime of the scat tering in the laboratory. This can act as a new generation of accelerator- based hard X/γ-ray sources driven exclusively by laser light. One ultrahi gh intense CPA laser pulses will act as two means: first used to accelerat e electrons by laser driven wake field (LWFA) to hundreds MeV\, and second \, from split beam or LWFA-leftover energy reflected by plasma mirror\, to collide on the electron for the generation of X/γ-rays. Such all-laser-d riven X/γ source have recently been demonstrated to be energetic\, tunabl e\, narrow/broad in bandwidth\, short pulsed and well collimated. Such cha racteristics\, especially from a compact source\, are highly advantageous for numerous advanced X-ray applications.

We have developed a 3 MeV ultrafast electron diffractio n (UED) probe technology that nominally reduces the electron bunch duratio n and the arrival time jitter to the sub-femtosecond level. This simple co nfiguration uses a radiofrequency photogun and a 90° achromatic bend and is designed to provide effectively jitter-free conditions. THz streaking m easurements reveal an electron bunch duration of 25 fs\, even for a charge as high as 0.6 pC\, and an arrival time jitter of 7.8 fs\, the latter lim ited only by the measurement accuracy. From pump-probe measurements of pho toexcited bismuth films\, the instrument response function was determined to 31 fs. Recently\, we proposed a simple way to further compress the elec tron bunch duration to sub-10 fs based on installing an energy filter in t he dispersion section of the achromatic bend. Through numerical simulation s\, we demonstrate that the electron bunches can be compressed\, at the sa mple position\, to a 6.2 fs duration for a 100 fC charge. This result sugg ests that the energy filtering approach is more viable and effective than complicated beam-shaping techniques that commonly handle the nonlinear dis tribution of the electron beam. \nIn an attempt to design smaller THz free -electron laser (FEL) devices capable of producing higher output powers in the THz spectral region of 1-2 THz\, we have developed a microtron accele rator that can accelerate electron beams from 3-6 MeV\, with a measured ma cropulse current of more than 40 mA. The new THz FELs use hybrid electroma gnetic (EM) undulators that are two to four times shorter in length than t he previous 2-m-long undulator and waveguide resonators with mode cross-se ctional areas that are more than two times smaller than the parallel-plate waveguide in the existing FEL. We confirm that the gains and losses of th e more compact FELs are sufficient for lasing\, and we estimate that an av erage output power of approximately 1 W is possible with an efficiency app roximately 10 times greater than the existing FEL. The minimum size of the THz FEL system\, including a high-voltage pulse modulator\, is estimated to be approximately 1.5 m × 2.0 m.\n\nhttps://indico.inp.nsk.su/event/42/ contributions/2147/ LOCATION:Zoom 1 URL:https://indico.inp.nsk.su/event/42/contributions/2147/ END:VEVENT BEGIN:VEVENT SUMMARY:Compact FEL-THz facility at IUAC – commissioning and initial tes ting of the sub-systems DTSTART;VALUE=DATE-TIME:20210317T062500Z DTEND;VALUE=DATE-TIME:20210317T065000Z DTSTAMP;VALUE=DATE-TIME:20260307T091801Z UID:indico-contribution-42-2133@indico.inp.nsk.su DESCRIPTION:Speakers: Subhendu Ghosh (Inter University Accelerator Centre) \nThe compact THz-FEL facility\, based on the RF photocathode electron gun \, is under the commissioning stage at Inter University Accelerator Centre (IUAC)\, New Delhi. Once operational\, it will be the first pre-bunched F EL facility in India and will be among the few in the world [1\,2]. The co mplete accelerator facility will be ~ 5 meters long and will deliver inten se THz radiation as well as an electron beam for doing experiments in the multidisciplinary fields. The electron gun\, powered by a Klystron/Modulat or\, is expected to generate an accelerating field of ~ 120 MV/m (max.) wh ich will produce an electron beam of energy of ~ 8 MeV. The electron beam\ , after being focused by solenoid and quadrupole magnet\, will be injected into a compact undulator to produce THz radiation in the frequency range of 0.18 to 3.0 THz. \nThe various subsystems of the THz facility are eithe r commissioned or in their final stage of installation. The cavity\, the w aveguides and the Klystron/Modulator have been commissioned and the RF con ditioning of the electron gun is presently on. The beam line is installed up to the entrance of the Undulator with the majority of the equipment alr eady installed and aligned. The undulator has arrived at IUAC from Deutsch es Elektronen-Synchrotron (DESY)\, Germany and will be commissioned in the beam line shortly. The photocathode deposition chamber and the fiber lase r system are in the final stage of testing at Brookhaven National Laborato ry\, USA and at High Energy Accelerator Research Organization (KEK)\, Japa n\, respectively. They are expected to arrive at IUAC in the next few mont hs. The electromagnets (dipole\, quadrupole and steering) were developed\, characterized at Bhaba Atomic Research Centre and were received at IUAC. \nAfter the installation of the fiber laser system at IUAC\, the cavity wi ll be conditioned with the Copper photocathode plug and the electron beam will be produced from the electron gun. The THz radiation will be demonstr ated subsequently\, by injecting the same electron beam into the compact u ndulator. It is likely that both the events will take place by the end of 2021.\nThe status of the commissioning of the facility and the testing of the various subsystems of the accelerator will be presented in the AFAD wo rkshop. \n\nReferences\n1.

For this purpose\, the electron beam is generated in an RF photocathode-based electron gun by irradiating the photocathode with la ser light. Typically\, a few tens of femtosecond laser systems are routine ly used to generate a pre-bunched electron beam of a few hundred femtoseco nds. Recently a novel Yb-dopped fiber-based laser system with enhanced tun ability and stability is being developed under KEK-IUAC collaboration to g enerate the electron beam for the compact THz facility of IUAC. The laser system can potentially deliver MHz-GHz-THz sequence of femtosecond pulses which populates every RF window (typically Hz rate) energizing the photoca thode-based electron gun and generates a low emittance electron beam of th e identical temporal structure.

The hadron driver in the proposal is based on a fast cycling i nduction synchrotron. Its main features are injector free\, multi species of ion acceleration capability\, fast cycling at 10 Hz repetition rate\, e nergy varying 1 turn fast extraction and energy sweep extraction. These ex traction mechanisms are designed specifically for treatment purpose. In th e fast extraction mode\, C+6 ions are extracted at any desired energy in e ach acceleration cycle. The extraction is assisted by an off momentum bump orbit of ions with a combination of a kicker and septum magnet. In the en ergy sweep extraction mode\, C+5 ions are continuously leaked from the bar rier bucket at desired energy and those C+5 ions drift inwards in the larg e dispersion region. A thin stripper foil is placed far from the center or bit of barrier trapped beam and C+5 ion hitting the foil edge gets conver ted into C+6 ion.

The fraction of such particles is small compared to all plasma electrons. We calculate fas t plasma electrons with full equations of motion when their Lorentz gamma factor exceeds trapping threshold.

A dielectric is therefore the choice of material for an accelerator operating at the optical frequencies. A dielec tric laser accelerator has the potential of stable high-gradient electron acceleration over a long distance. Owing to the much shorter drive wavelen gth\, a dielectric laser accelerator could also produce very short electro n bunches useful for studying attosecond science or generating EUV superra diance. The inverse process of particle acceleration is particle radiation . In this presentation\, we will show various mechanisms to generate laser -like radiation from a beam-driven dielectric structure by a small account of charge. The coherent radiation by itself is useful for applications.

It mainly consists of three parts including a linac\ , a booster and a collider. That CEPC booster needs to boost the beam ener gy from 10 GeV to 45.5 GeV brings many difficulties to fabricate and measu re the dipole magnet. One of the practical way to avoid the low field dipo le issue of the booster is to introduce the CEPC Plasma Injector (CPI) to boost the beam energy before injecting the beam into the booster.\nIn this work\, we present preliminary studies on CPI\, including simulation studi es on electron acceleration with high transformer ratio and new schemes fo r positron acceleration. In addition\, we also present some experimental r esults on plasma dechirper at THU lab.\n\nhttps://indico.inp.nsk.su/event/ 42/contributions/2203/ LOCATION:Budker INP URL:https://indico.inp.nsk.su/event/42/contributions/2203/ END:VEVENT BEGIN:VEVENT SUMMARY:LGAD Based Endcap Timing Layer for CMS phase-2 upgrade DTSTART;VALUE=DATE-TIME:20210317T072000Z DTEND;VALUE=DATE-TIME:20210317T074000Z DTSTAMP;VALUE=DATE-TIME:20260307T091801Z UID:indico-contribution-42-2201@indico.inp.nsk.su DESCRIPTION:Speakers: Sunil Dogra (Kyungpook National University)\nThe Com pact Muon Solenoid (CMS) detector at the European Council for Nuclear Rese arch (CERN) Large Hadron Collider (LHC) is undergoing an extensive Phase I I upgrade program to prepare for the challenging conditions of the high-lu minosity LHC (HL-LHC).

Photons inciden t onto the photocathode are converted to photo-electrons. Then the photo-e lectrons are accelerated toward the scintillator by the electric field bet ween the photocathode and electrode to produce scintillation lights. The s cintillation lights are incident on the SiPM to be converted to photo-elec trons\, which are subsequently multiplied to 106 electrons or more by the avalanche process inside SiPM. The advantage of this type of photo-detecto r is that the scintillation lights contribute an extra gain in the order o f tens in addition to the existing gain of 106 or higher from the SiPM. Th is type of photo-detector with a large area of photocathode could be used in photo-detector array for neutrino detection.

An experiment reaches the neutrino floor went it becomes so large an d so sensitive that the background from coherent nuclear scattering of ast rophysical neutrinos starts to drown out a potential dark matter signal. T he encroachment of the neutrino floor has driven an increase in interest t owards a technique which has the potential to circumvent the limit entirel y: directional detection. The technique aims to measure the strongly aniso tropic angular distribution of the dark matter wind incident on Earth as w e journey around the Milky Way galaxy. The potential for dark matter disco very with directional detectors greatly exceeds that of conventional detec tors\, so the concept is well worth investigation if we 1) want to extend the search for dark matter below the neutrino floor\, or 2) wish to confir m a potential signal of dark matter without relying on the controversial a nd systematic-prone annual modulation. While in practice directional detec tors are several years away from being at a competitive scale\, there seve ral promising approaches under investigation.

Lately few upgrades and addit ions have been carried out for some of the pulse sources in Indus-2. In th is talk\, these upgrades / additions to pulse sources in Indus-2 will be d iscussed. Pulse sources to energise Indus-2 Injection kicker magnets are w orking in the machine for last 15 years. These pulse sources are working i n the machine in severe space constraints with large pulse power assemblie s in oil tanks and any maintenance or on site measurements is very cumber some for the working personnel attending it. So it was planned to design a nd develop new pulse source with an upgraded design. Efforts were made to reduce the working voltages in the new design and thereby remove the oil a ssemblies. Pulse source has been designed and developed to deliver 6 kA of peak current with a half sine pulse width of 3usec. in Indus-2 kicker mag net as load. Repetition rate of pulse is 1 pulse per second. Developed pul se source has been tested with Indus-2 kicker magnet in lab. \n Also it was decided to equip Indus-2 with two pinger kicker systems. Pi nger kicker system will consist of two types of kickers namely horizontal and vertical pinger kicker. These pinger (kicker) magnets are energized by two separate pulse sources. These kickers will generate betatron oscillat ion in the stored beam (few bunches) of Indus-2 in a synchronised operatio n. The kickers will act as a tool to probe the linear and non linear dynam ics of the beam. The turn by turn oscillations of the beam are captured by beam position monitors of the ring. Two pulse sources to energise these k icker magnets respectively has been developed. Vertical pinger kicker syst em has already been installed in the ring. Horizontal pinger pulse source development has also been completed and the same has been tested with kick er magnet in lab. Installation and commissioning of horizontal kicker syst em in Indus-2 ring is also planned shortly. Technical requirement of these pulse sources\, their development and test results will also be discussed in this talk.\n\nhttps://indico.inp.nsk.su/event/42/contributions/2195/ LOCATION:Zoom 1 URL:https://indico.inp.nsk.su/event/42/contributions/2195/ END:VEVENT BEGIN:VEVENT SUMMARY:Dual-Readout Calorimeter R&D in Korea for future e+e- colliders DTSTART;VALUE=DATE-TIME:20210317T074000Z DTEND;VALUE=DATE-TIME:20210317T080000Z DTSTAMP;VALUE=DATE-TIME:20260307T091801Z UID:indico-contribution-42-2197@indico.inp.nsk.su DESCRIPTION:Speakers: Hwidong Yoo (Yonsei University)\nThe dual-readout me thod is a state of the art calorimetry technique enables high-quality ener gy measurement for both electromagnetic and hadronic particles\, which has been developed during last two decades.

For the HBSRS \, the beam emittance of 150 pm rad at the beam energy of 6 GeV is conside red assuming 7 bend achromatic (7MBA) type lattice configuration. The PMK magnet provides transparent top up injection\, since these magnets have ze ro magnetic field at their center where the stored beam is passing does no t receive perturbation. The injected beam is captured into the storage rin g acceptance by a kick of the PMK magnet. For the beam injection studies\, a single pulsed sextupole magnet (PSM) as well as non-linear kicker (NLK) magnet scheme is explored. In view of achieving more than 90 % injection efficiency\, optimal strength of PSM magnet and acceptable tolerance such as injection angle errors and field strength error are estimated using tra cking-based simulation code ELEGANT. The alignment errors of PSM produced unwanted kicks to the stored beam and produces the stored beam oscillation . The alignment tolerance studies for keeping the stored beam oscillation within 10 % of beam size has been studied.

But\, one uncomfortable feature is to be broken due to a large discharge. One large charge deposit makes a trigger to lead the large discharge and to carbonize inside the GEM hole . In order to avoid such a bad situation\, we are developing new GEM foil without carbon. One good solution is to apply ceramic as an insulator inst ead of Polyamide and Liquid Crystal Polymer (LCP). New ceramic GEM was man ufactured with 100 mm × 100 mm size and 100 m thickness. Also\, a neu tron detector was constructed with a hybrid cathode to detect both thermal (or cold) neutron and MeV neutron. The hybrid cathode consists 0.5mm PET (Polyethylene Terephthalate) plate with 1 m boron layer. Thermal neutro n can be absorbed in the boron layer and can produce alpha particle (and L i nuclei). The cross section of boron for the MeV neutron is too small. It is better to select another material to detect the MeV neutron. The MeV n eutron can easily hit the hydron inside of material and can produce the pr oton. On good candidate is PET\, which contents large amount of hydrogen. The cathode was fabricated by ourself and installed in the chamber with si ngle GEM structure. The chamber is work fine. Now\, we are trying to make boron coated GEM to get higher efficiency for the thermal neutron. It will be available near future.\n\nhttps://indico.inp.nsk.su/event/42/contribut ions/2187/ LOCATION:Budker INP URL:https://indico.inp.nsk.su/event/42/contributions/2187/ END:VEVENT BEGIN:VEVENT SUMMARY:Cryogenics for SCRF Cavity Test Facilities DTSTART;VALUE=DATE-TIME:20210317T043000Z DTEND;VALUE=DATE-TIME:20210317T050000Z DTSTAMP;VALUE=DATE-TIME:20260307T091801Z UID:indico-contribution-42-2185@indico.inp.nsk.su DESCRIPTION:Speakers: Prabhat Gupta (RRCAT Indore)\nVertical Test Stand (V TS) and Horizontal Test Stand (HTS) Facilities are set-up at RRCAT for tes ting and qualification of Superconducting Radio Frequency (SCRF) Cavities.

The superfluid helium bath cools the niobium superconducting radio frequency (SRF) cavities housed in the helium tanks of the cryomodules. Th e SRF cavities operate at temperatures of 2.0 K or below\, due to its high er operating frequency like 1.3 GHz. At KEK\, the superfluid helium cryoge nic plants produce superfluid helium continuously by isenthalpic expansion of the normal liquid helium (LHe) (~4.4 K) through a Joule-Thomson (JT) v alve\, which is connected in series with a 2K heat exchanger (2K HX). The 2K HX recovers the coldness from the 2.0 K gaseous helium (GHe) evaporatin g from the helium tanks of the SRF cavities. This increases the production rate of the superfluid helium by reducing the incoming LHe temperature fr om 4.4 K to 2.2 K or above\, before the JT valve. As such\, reducing the v apor flash losses from 40% to 9.4%\, during the JT expansion to produce 2. 0 K saturated superfluid helium. At KEK\, we have a 2K HX consisting of a helical coil and laminated fins. Its performance is determined and charact erized by a factor known as “effectiveness”\, which is the ratio of ac tual heat transfer to the maximum possible heat transfer between the fluid s. To produce ~2.2 K LHe at the outlet of the 2K HX and before the JT valv e\, the required effectiveness is > 84%. A numerical model has been develo ped to determine the performance parameters (effectiveness and GHe pressur e drop) of the current 2K HX design and is verified experimentally using a heat exchanger test stand. Furthermore\, a parametric study is conducted to improve the performance of the current 2K HX design\, which was also va lidated experimentally. The improved 2K HXs were studied in conjunction wi th the GHe pumping system to determine the optimal 2K HX design that maxim izes the He II production from the cryogenic systems.\n\nhttps://indico.in p.nsk.su/event/42/contributions/2151/ LOCATION:Budker INP URL:https://indico.inp.nsk.su/event/42/contributions/2151/ END:VEVENT BEGIN:VEVENT SUMMARY:Cryogenic system of superconducting wigglers and undulators develo ped by BINP DTSTART;VALUE=DATE-TIME:20210316T063000Z DTEND;VALUE=DATE-TIME:20210316T070000Z DTSTAMP;VALUE=DATE-TIME:20260307T091801Z UID:indico-contribution-42-2149@indico.inp.nsk.su DESCRIPTION:Speakers: Vitaliy Shkaruba (BINP)\nOver 20 years more than 25 superconducting multipole insertion devices for generation of synchrotron radiation (wigglers and undulators) have been created at BINP for several synchrotron radiation centers.
