本文介绍的大张角Bragg探测器的张角为±8°的锥形腔体。在整个探测器的灵敏区内,电场是均匀场。用ThC-ThC′源的α粒子(8.785MeV)测试,其能量分辨率为0.8％,电荷数分辨率为1.8％。
This article describes the wide angle Bragg detector angle of ± 8 ° cone chamber. The electric field is uniform across the detector’s sensitive area. With a ThC-ThC ’source of alpha particles (8.785 MeV) tested, the energy resolution was 0.8% and the charge resolution was 1.8%.
