GDB-15型光电倍增管结构紧凑、坚实。管子外径为14mm,阴极有效直径最小为9mm,长度为84±2mm; 采用半透明锑钾铯阴极、直线聚焦结构,有10个锑碱倍增极,是一种新型的超小型光电倍增管。
The GDB-15 photomultiplier tube is compact and solid. The outer diameter of the tube is 14mm, the minimum diameter of the cathode is 9mm, and the length is 84 ± 2mm. The translucent antimony potassium cesium cathode adopts a straight focusing structure with 10 antimony and alkali doping poles. It is a new type of ultra-small photomultiplier tube.
