本文描述一个以屏栅电离室作△E探测器,以Au-Si面垒探测器测定核粒子剩余能量E_R的△E-E计数器望远镜,如图1所示。作为阴极而处于地电位的壳体是由黄铜加工而成的。入射窗架固定在前盖板上,它同时又充当入射粒子的准直孔(φ4 mm×40 mm)。 This paper describes a △ E-E counter telescope with screen-ionization chamber as △ E detector and Au-Si surface-barrier detector as the residual energy E_R of nuclear particles, as shown in Fig.1. The housing, which is at ground potential as a cathode, is machined from brass. The entrance window frame is fixed on the front cover, and at the same time it acts as the collimation hole (φ4 mm × 40 mm) of the incident particle.
