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.

A test experimental line at SPring-8 has been constructed for the generation of backward Compton scattered (BCS) $$gamma$$-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 ($${rm CO}_{2}$$) laser. The FIR laser output power achieved is 1.6 W at maximum for 118.8 $$mu$$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 $$gamma$$-ray flux was found to be about $$10^{3}$$ 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.

The Research Center for Nuclear Physics (RCNP) at Osaka University is planning to increase the intensity of the high-energy white neutron field that can be used to analyze semiconductor soft errors caused by cosmic ray-derived neutrons. Using the PHITS code, we had designed and installed a neutron-producing target, beam dumps, collimators, etc., applicable to the 392 MeV proton beam with 10 times higher intensity (about 10$${mu}$$A) than the current one. In this study, the accuracy of the PHITS simulations was confirmed based on the data measured at the real facility. The simulation geometry was constructed according to the drawings of the facility. The INCL model and JENDL-5 were used for the radiation transport simulations. Neutron and gamma-ray dose rates were measured at several locations using the Wendi-2 and DARWIN monitors. As a result, PHITS well reproduced the neutron fluence rates at the semiconductor irradiation location, and the simulated values agreed with the measured neutron and gamma-ray dose rates within 5 and 15%, respectively, behind the shielding.
