Abstract
Energy and flux of positrons and neutrons generated in the electron storage ring NewSUBARU by laser Compton scattering with Nd (1.064 μm,) laser beams were measured. The energy of positrons was measured with an imaging plate. The positron energy has a peak around 10 MeV. With a 3 mm thick Pb target, about 3600 positron sec-1 can be generated and the maximum generation rate of 0.0436 positron photon-1 can be obtained under the top-up mode operation. The generation rate is defined to be the number of positrons generated per the incident single gamma-ray photon. The energy of neutrons was measured with a time of flight. The maximum neutrons energy is around 8 MeV which agreed well with the obtained result 8.6 MeV.
