位置灵敏布喇格探测器的研制

Study on Position Sensitive Bragg Detector

本文介绍我们研制的一台用于重离子鉴别的位置灵敏布喇格探测器，它是在普通布喇格探测器的Ｆｒｉｓｃｈ栅和阳极之间加进一个辅助栅──—Ｐ栅．位置信号从Ｐ栅上提取，位置由丝确定，用电荷分除法来进行位置读出。其性能用￣（２５２）Ｃｆａ源进行了测试。

A position sensitive Bragg Curve Spectroscopy(PS-BCS)for heavy ion identification isintroduced in this paper.The position signal is extracted via an auxiliary grid(P grid)betweenthe anode and the Frisch grid.The position is determined by the wires. The charge divisionmethod has been used for position read-out. The test results of the detector with ￣(252)Cf a sourcehave shown a position resolution △x <9mm.(
