摘要：In this work we report on the time performance of single-gap and double-gap timing Resistive Plate Chambers (tRPCs) with 10 MeV electron bunches at the electron accelerator of the CEA/DAM/DIF (Commissariat à l’énergie atomique, Military Applications Division, Île de France) and with 500 A×MeV 136Xe ions accelerated by the SIS18 synchrotron at GSI (Helmholtzzentrum für Schwerionenforschung). The measurements with electrons show a clear dependence of the time resolution with the beam intensity, reaching values below 30 ps (s). On the other hand, a time resolution of about 45 ps is obtained for the single-gap tRPCs with the xenon beam, but it worsens when we increase the event rate above several Hz/cm2.
