We constructed MeV- and sub-MeV-photon sources by means of Compton backscattering with a laser light and an electron beam at SPring-8 and KPSI-JAEA. MeV-photon source consists of a continuous-wave optically-pumped far infrared laser and an 8-GeV stored electron beam. Sub-MeV-photon source consists of a Nd:YAG pulse-laser and an 150-MeV electron beam accelerated by a microtron. Both source have been succeeded backscattered photon generation. In this talk, I will present characteristics and future prospects of these photon sources.

Times Cited Count:20 Percentile:77.77(Instruments & Instrumentation)A test experimental line at SPring-8 has been constructed for the generation of backward Compton scattered (BCS) -ray by head-on collision between an 8 GeV electron beam and a far-infrared (FIR) laser. For the FIR laser, we use a continuous-wave methanol laser optically pumped by a carbon dioxide () laser. The FIR laser output power achieved is 1.6 W at maximum for 118.8 m lasing; this value is the highest in the case of this type of laser. As a result of the direct measurement, the generated BCS -ray flux was found to be about photons/s. This value is consistent with the estimation calculated by taking into account the input laser power and the transmittance of the laser transport system.
