64通道一维位置灵敏电流分布探测器及其数据获取系统

针对高流强粒子束与绝缘毛细管相互作用的特点， 设计制作了一套64通道一维位置灵敏电流分布探测器及其配套的数据获取系统， 该探测器可分辨最小直径为1 mm的束斑， 通过数据获取系统可实现可视化自动数据采集。 用2 nA和200—2000 eV电子对探测器进行了定标， 并用10 μA和2000 eV的电子束穿越锥形毛细管后的出射电子， 对探测器及数据获取系统进行测试， 获得了出射粒子的位置分布谱及能量信息。 A 64 channel position sensitive current distribution detector with 1 mm position resolution was developed， while the data acquisition system is based on the LabVIEW software. The test result obtained by using a 2 nA， 200—2000 eV electron beam deflecting by different voltages and the position spectra of 10 μA， 2000 eV electrons transmitted through a glass capillary was measured. The result indicated that the detector can be used to detect the charged particles with strong beam current through the capillary.
