There are wel l-known Hall probe and moving wire based methods. This paper describes cur rent driven wire based method. A thin nonmagnetic wire is strained within the wiggler. It is secured and tighten on supports located in some distanc e from the wiggler. Wire position sensors are located on the wiggler sides . Current applying to the wire deflects it according to the magnetic field inside the wiggler. There are a number of current modes giving different information. Constant current method gives 1-st and 2-nd magnetic integral s\, median plane position\, sextupole integral. Vibrating current method ( multiple by wire self-resonant frequency) gives any integral with higher s ensitivity. Pulse wire method is alternative to Hall-probe method.\n\nhttp s://indico.inp.nsk.su/event/3/contributions/1162/ LOCATION:Budker INP Conference Hall URL:https://indico.inp.nsk.su/event/3/contributions/1162/ END:VEVENT BEGIN:VEVENT SUMMARY:3D X-ray lithography DTSTART;VALUE=DATE-TIME:20160707T074000Z DTEND;VALUE=DATE-TIME:20160707T080000Z DTSTAMP;VALUE=DATE-TIME:20260316T054340Z UID:indico-contribution-135-1203@indico.inp.nsk.su DESCRIPTION:Speakers: Vladimir Nazmov (Budker Institute of Nuclear Physics )\nAn increased depth of the transformed material\, due to the low absorpt ion of materials to X-rays\, was one of the main advantages of the X-ray l ithography for the photolithography and for the electron beam lithography. But\, this property was an obstacle to its further development concerning 3D patterning. Practically\, all the created by X-ray lithography so-call ed 3D structures [A.del Campo\, C.Greiner. SU-8: a photoresist for high-as pect-ratio and 3D submicron lithography\, J.Micromech.Microeng.\, v.17(200 7) R81-R95] are really 2D+ structures. In this work\, a concept of manufac turing of real 3D structures is proposed. At the same time\, the high spat ial resolution of the method is kept. Using a high-contrast X-ray resist\, 3D microstructures of various forms and sizes are created. The smallest m icrostructure achieve a size of about 0.3 microns.\n\nhttps://indico.inp.n sk.su/event/3/contributions/1203/ LOCATION:Budker INP Conference Hall URL:https://indico.inp.nsk.su/event/3/contributions/1203/ END:VEVENT BEGIN:VEVENT SUMMARY:Metrological station "Cosmos".

In view of the global switch to the f ourth generation of synchrotron sources and X-ray Free Electron Lasers\, t here is a growing need for x-ray optical elements fabricated from material s that can withstand extreme heat and radiation loads while still providin g effective focusing and imaging. Diamond can satisfy all the requirements provided that a suitable lens manufacturing technology is available. \n\n In our research [2]\, for the first time single crystal diamond planar ref ractive lenses were fabricated by laser micromachining in up to 1.2 mm th ick diamond plates which were grown by CVD and HPHT. Various linear lenses with apertures up to 1mm and radii of the parabola apex up to 500µm were manufactured and investigated with SEM\, AFM\, Raman spectroscopy and\, o f course\, X-ray tests at the ESRF ID06 beamline. X-ray focusing showed th e high quality of the lens’s side walls and profile allowing to focus th e X-radiation in accordance with the lens demagnification factor. \nPlanar lenses were followed by 2D parabolic X-ray refractive half lenses\, which were also manufactured by laser micro-machining of single-crystal diamond . A single 2D lens had an aperture of 1 mm and parabola apex radii of 200 µm. Forming a compound refractive lens with 24 single lenses within\, it has been successfully tested in the focusing and imaging modes both at the APS source [3] and at the laboratory setups using Cu Kα X-radiation from the rotating anode generator and microfocus MetalJet X-ray tube with a li quid-gallium jet as the anode using Ga Ka line. The lens has successfully reproduced the triangular object with the theoretical demagnification whil e the focusing of the 20 µm source was performed with the small deviation from the theoretical value. \n\nThe present study demonstrated that laser micro-fabrication technology provides a straight forward method for the f abrication of single-crystal diamond refractive lenses with large acceptan ce and high shape and surface (peak-to-valley roughness ~ 1µm) quality. U nique optical properties of diamond single-crystal lenses (the refractive index decrement\, δ\, in diamond is double that of beryllium) coupled wit h its excellent thermal qualities (high thermal conductivity and shock res istance\; low thermal expansion coefficient\; high temperature stability) allow them to be applied as focusing\, imaging and beam-conditioning eleme nts at high-heat flux beams of today and future X-ray sources.\n\n**Refere nces**\n\n 1.

The concept of the proposed microscope is based on employing compound refractive lense s allowing to retrieve high resolution diffraction pattern and real-space images in the same experimental setup [1-4]. This idea\, well-known for th e studies of crystals by high resolution transmission electron microscopy\ , is the key ingredient of our approach.\nThe microscope operates under a coherent illumination where a diffraction pattern of the specimen is forme d in the back focal plane of the condenser and an inverted two-dimensional image of the object is formed by objective lens in the image plane [5]. T he diffraction mode is used to investigate the structure over the macrosco pic distances and to orient the crystals parallel to the low index directi on to perform high-resolution imaging on the local scale. The image format ion relies on phase contrast due to the interference of several diffracted beams [6]. A high spatial coherence is needed in the imaging mode to ensu re a reasonable contrast. The coherence in terms of the angular source siz e determines the lens angular resolution (\n\nhttps://indico.inp.nsk.su/ev ent/3/contributions/1311/ LOCATION:Budker INP Conference Hall URL:https://indico.inp.nsk.su/event/3/contributions/1311/ END:VEVENT BEGIN:VEVENT SUMMARY:Performance and characterisation of CsI:Tl thin films for X-ray im aging application DTSTART;VALUE=DATE-TIME:20160707T094000Z DTEND;VALUE=DATE-TIME:20160707T100000Z DTSTAMP;VALUE=DATE-TIME:20260316T054340Z UID:indico-contribution-135-1317@indico.inp.nsk.su DESCRIPTION:Speakers: evgeny kozyrev (binp)\nWe developed method of thin s cintillator films preparation based on thermal CsI(Tl) deposition on glass substrates. The influence of deposition conditions on the micro columnar structure and crystalline property of the films was studied by scattering electron microscopy. The element composition was investigated by X-ray flu orescence method. We measured light output and spacial resolution as a fun ction of input photons energy (5-35 keV) and film thickness (2-20 mkm). It was observed the strong anti-correlations between the time of CsI(Tl) dep osition\, film light output and thallium concentration. The films can be u sed for charged particles beams monitoring as well as for X-ray imaging ap plications including micro tomography and topography.\n\nhttps://indico.in p.nsk.su/event/3/contributions/1317/ LOCATION:Budker INP Conference Hall URL:https://indico.inp.nsk.su/event/3/contributions/1317/ END:VEVENT END:VCALENDAR
