100MeV/u α粒子入射荷電粒子生成二重微分断面積の測定

抄録

Radiation transport simulation codes are used to make an assessment of proton and heavy ion radiotherapies and to make a calculation of Radiation shield for medical accelerator facilities. Double differential cross section (DDX) of charge particle production is one of the important elements to assess and improve such simulation codes. We investigated Electric charge particle production DDX using 100MeV/u alpha particle beam on aluminum and cobalt targets. Charge particle DDX haven’t been reported for alpha of 100MeV/u incident reaction. Emitted charge particle’s energies were measured with spectrometer consisting of NE102 detectors, BSO crystal scintillation detector, and PWO crystal scintillation detector by the ΔE-E technique. The experimental data of DDX were compared with radiation transport simulation code PHITS.
