Abstract

Fast and precise scintillating fiber tracker (SciFi), using 0.5 mm diameter fibers (Kuraray SCSF-78MJ) and position-sensitive photomultiplier tubes (Hamamatsu H6568), has been developed for COMPASS (NA58) experiment at CERN. Tests of a 16-channel prototype showed an excellent stability in time resolution, in spatial resolution as well as in detection efficiency under different beam flux of up to 1.4/spl times/10/sup 8/ muons/spill. Four SciFi stations have been constructed and all of them are presently under operation in the experiment with high performances as expected from the prototype.

用于高速率实验的高时间分辨率闪烁光纤跟踪器

采用0.5 mm直径的Kuraray SCSF-78MJ光纤和位置敏感光电倍增管Hamamatsu H6568，为欧洲核子研究中心(CERN)的COMPASS (NA58)实验开发了快速精确的闪烁光纤跟踪器(SciFi)。对16通道原型机的测试表明，在不同的光束通量下，该系统在时间分辨率、空间分辨率和检测效率方面具有优异的稳定性，最高可达1.4/spl次/10/sup 8/ μ子/溢出。目前已建成4个科幻站，所有科幻站均在试验中运行，其性能均达到了样机的预期水平。
