MULTI-GAP RESISTIVE PLATE CHAMBER—A NEW TYPE OF DETECTOR FOR TIME OF FLIGHT

摘要

A Time-of-Flight tray with 28 6-gap MRPC modules was tested at AGS and then installed in STAR for the RHIC 2003 physics run after a series of module R&D. Results show clear identification of K/π up to 1.6 GeV/c and proton/K up to 2.9 GeV/c. In addition, electrons can be clearly identified by combining the dE/dx information from the TPC with the TOF detector.
