摘要：Multi-gap resistive plate chambers (RPCs) are proposed to build the Time-of-Flight wall of the Compressed Baryonic Matter experiment with a time resolution better than 80 ps. The high fluxes expected at the innermost part of the detector, 20103 cm2 s1 require the development of new materials capable of withstanding such fluxes. At Helmholtz-Zentrum Dresden-Rossendorf, several RPC prototypes of 1010 cm2 and 2020 cm2 have been built with ceramic plates with bulk resistivities in the range of 109-1010 W cm [1]. They have been tested at the superconducting electron accelerator facility ELBE with 30 MeV electrons. We present the characteristics of the ceramic electrodes and the latest results concerning the performance of these prototypes in electron and protons beams up to fluxes of 106 cm2 s1.
