| Research Abstract |
A prototype detector for solar gamma rays and neutrons are developed and investigate its characteristics. The detector is construct of a unity with plastic and LiI scintillators and a Photomultiplier tube. Gamma-ray, neutron and charged particle (cosmic ray) can be distinguished by differences of light emission due to decay time of each scintillator and particle reaction in the scintillators. The energy resolution of gamma-ray is about 11% at 661keV. An energy spectrum of neutrons from a radioactive source from 1 to 8 MeV is consistent with a simulation result taking the detector construction into account.
