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，得到位置分辨△ｘ＜９ｍｍ
This article introduces a locationally sensitive Bragg detector we have developed for heavy ion identification, which adds an auxiliary gate-P-gate between the Frisch gate and the anode of a conventional Bragg detector. The position signal is extracted from the P-grid, the position is determined by the filament, and the position is read out by the charge-division method. Its performance was tested with a ~ (252) Cfa source, resulting in a position resolution of Δx <9mm
