Abstract

A lost alpha particle-induced gamma ray detector system is now under development for application to ITER. The Ce:LSO scintillator is considered an attractive candidate detector and its characteristics were studied. To evaluate the potential of this system, the pulse height distribution of 4.44 MeV gamma rays resulting from an Am-Be source was measured, and results obtained by experiment and EGS4 simulation was compared. In addition, the transmittance of Ce:LSO was measured to evaluate the effects of self-absorption.
