- For many applications of RPCs to time-of-flight counters in heavy ion experiments the expansion to much higher values of the counting rate capability, so far limited to around 2 kHz/cm(2) is of fundamental importance. To address this issue we developed single-gap timing RPCs with resistive electrodes made from a commercially available plastic material. Tests performed in photon beams yielded a time resolution around 90 ps sigma, essentially unchanged from 2 kHz/ cm(2) to 27 kHZ/cm(2). This result establishes the basic feasibility of timing measurements with RPCs at rates of tens of kHZ/cm(2), keeping a time resolution below 100 ps a and using plastic electrode materials.
