  840MeV SXFEL is the first soft X-ray FEL built in Shanghai, now it’s in the commissiong stage. Also in Shanghai light source, a Hard X-ray 8GeV CW FEL has been proposed many years ago, and presumably will be approved in 2018.

 Linac Based Light Source Activities at THU  
 
  • Y. C. Du, L.X. Yan
    TUB, Beijing, People’s Republic of China
  
  The high brightness electron linac based on a photocathode RF gun was established in Tsinghua University for the study of Thomson scattering x-ray and THz radiation light sources. Recent THz radiation research activities with tunable bunch trains, specially on their generation and diagnostics, will be presented. Experiments on coherent undulator radiation, coherent transition radiation, coherent Smith-Purcell radiation, dielectric wakefield radiation were performed. Another part of this talk will be focused on the recent progress in linac based ICS source at Tsinghua University, including the experiments on X/gamma-ray generation, diagnostic, and its applications in advanced X-ray imaging. And the design of a new compact ICS gamma-ray sources will also be discussed in this talk.

  ELI-NP gamma beam system (GBS) is a linac based gamma-source in construction in Magurele (RO) by the European consortium EuroGammaS led by INFN. Photons with tunable energy, from 0.2 to 19.5 MeV, and with intensity and brilliance beyond the state of the art, will be produced by Compton back-scattering between a high quality electron beam (up to 740 MeV) and an intense laser pulse at 100 Hz repetition rate. Production of very intense photon flux with narrow bandwidth requires multi-bunch operation and laser recirculation at the interaction point. In this paper, the main technological developments carried out by the EuroGammaS consortium for the generation of the ELI-NP gamma beam will be described with a special emphasis on the electron linac technology, such as: RF-gun and C-band accelerating structures design fabrication and tests; low level RF (LLRF) and synchronization systems specifications and development. Finally, the laser recirculation apparatus design is briefly described and first results reported.

  New designs for compact SRF linacs can produce micron-size electron beams. These can can be used for inverse Compton scattering light sources of exceptional flux and brilliance.
