Its wavelength can be tuned over a wide range in terahertz and infrared spectrum regions. As a source of e lectron bunches this FEL uses multi-turn energy recovery linac which has f ive straight sections. Three sections are used for three FELs which operat e in different wavelength ranges (the first one - 90-240 microns\, the sec ond - 37 – 80 microns and the third - 5 – 20 microns).\nThe first and the second FELs were commissioned in 2003 and 2009 respectively. They oper ate for users now. The third FEL is installed on forth accelerator track w hich is the last one and electron energy is maximal here. It comprises thr ee undulator sections and 40 m optical cavity. The first lasing of this FE L was obtained in summer\, 2015. The radiation wavelength was 9 microns an d average power was about 100 watts. The designed power is 1 kilowatt at r epetition rate 3.75 MHz. Radiation of third FEL has been delivered to user stations recently. \nThe third FEL commissioning results as well as curre nt status of the first and second FELs and future development prospects ar e presented.\n\nhttps://indico.inp.nsk.su/event/3/contributions/1154/ LOCATION:Budker INP Conference Hall URL:https://indico.inp.nsk.su/event/3/contributions/1154/ END:VEVENT BEGIN:VEVENT SUMMARY:Possibilities for future SR and FEL development in the UK DTSTART;VALUE=DATE-TIME:20160704T070000Z DTEND;VALUE=DATE-TIME:20160704T074000Z DTSTAMP;VALUE=DATE-TIME:20260712T182622Z UID:indico-contribution-138-1199@indico.inp.nsk.su DESCRIPTION:Speakers: Richard Walker (Diamond Light Source)\nPossibilities for future SR and FEL development in the UK\n\nhttps://indico.inp.nsk.su/ event/3/contributions/1199/ LOCATION:Budker INP Conference Hall URL:https://indico.inp.nsk.su/event/3/contributions/1199/ END:VEVENT BEGIN:VEVENT SUMMARY:Synchrotron radiation research and application at VEPP-4 DTSTART;VALUE=DATE-TIME:20160704T103000Z DTEND;VALUE=DATE-TIME:20160704T105000Z DTSTAMP;VALUE=DATE-TIME:20260712T182622Z UID:indico-contribution-138-1210@indico.inp.nsk.su DESCRIPTION:Speakers: Pavel Piminov (BINP SB RAS)\nPresently at VEPP-4 sto rage ring facility varied experimental programs are carried out including HEP\, nuclear physics\, synchrotron radiation and e+e− beams (polarized and unpolarized).\n\nhttps://indico.inp.nsk.su/event/3/contributions/1210/ LOCATION:Budker INP Conference Hall URL:https://indico.inp.nsk.su/event/3/contributions/1210/ END:VEVENT BEGIN:VEVENT SUMMARY:NSLS-II Booster DTSTART;VALUE=DATE-TIME:20160704T082000Z DTEND;VALUE=DATE-TIME:20160704T084000Z DTSTAMP;VALUE=DATE-TIME:20260712T182622Z UID:indico-contribution-138-1217@indico.inp.nsk.su DESCRIPTION:Speakers: Sergey Gurov (BINP)\nThe National Synchrotron Light Source II is a third generation light source\, which was constructed at Br ookhaven National Laboratory.

Special efforts were made by BINP to develop the cryogenic system w ith zero liquid helium consumption. The next significant step became the d esign and creation of superconducting full size prototype of dumping wiggl er for CLIC project where supposed the installation of 104 wigglers. For o peration of CLIC dumping wiggler it is required the magnetic field of 3 T and the period about 50 mm with a beam vertical aperture of 13 mm. Design features of the wiggler which was proposed and created by BINP is the app lication of the indirect cooling method. In this case Nb-Ti magnet with t he length of 1.8 m and the weight of 700 kg is located in a vacuum and is cooled by four Gifford-McMahon cryocoolers. To maintain the temperature a bout 4.2 K on the magnet it is used the tubes with circulating liquid heli um as the heat conducting elements. To increase the efficiency of pre-coo ling down of the magnet it is used nitrogen-based heat pipes of siphon typ e. The features of the magnetic and cryogenic systems of CLIC dumping wi ggler full size prototype and test results are presented in this article.\ n\nhttps://indico.inp.nsk.su/event/3/contributions/1234/ LOCATION:Budker INP Conference Hall URL:https://indico.inp.nsk.su/event/3/contributions/1234/ END:VEVENT BEGIN:VEVENT SUMMARY:Status of Siberian Synchrotron and Teraherz Radiation Center.

It is known that high-powe r THz beams can be controlled by silicon diffractive optical elements (DOE s) [2\,3\,4]. The lithographic etching of a silicon substrate [2\,3\,4] ha s disadvantages: fabrication of multi-level elements by lithographic etchi ng requires an expensive and complicated procedure of photomask alignment\ , and binary (two-level) elements have limited energy efficiency. A possib ility of the microfabrication of a high-effective power silicon diffractiv e optics for terahertz range by laser ablation is investigated [5]. A four -level silicon diffractive THz Fresnel lens has been fabricated for the fi rst time by femtosecond laser ablation [5]. High repetition (f = 200 kHz) femtosecond Yb:YAG laser was used for the formation of micro-relief at the silicon surface. Features of the lens were investigated in the beam of th e free electron laser at the wavelength of 141 µm. The measured diffracti ve efficiency of the lens is in good agreement with the theoretical predic tion [5]. \nThe experiments have shown the feasibility of laser ablation o f the silicon surface to fabricate effective multilevel THz DOEs. \nImprov ing the proposed technology of forming a silicon microrelief\, in particul ar increasing the number of its quantization levels\, will eventually incr ease the energy efficiency of silicon DOEs designed to control beams of TH z radiation.\n\n1.
