Cosmic-ray test of the installed endcap RPC modules in BELLE detector

摘要

In BELLE detector at KEKB, the resistive plate counter (RPC) modules were constructed for the muon trigger and K/sub L//sup 0/ detection. The endcap quadrant consisting of 14 superlayer RPC modules alternating with 47 mm thick iron plates and the 112 endcap modules have been installed in BELLE detector. We study on the tracking performance of the installed endcap RPC modules using by cosmic-ray test for the whole BELLE detector system.
