Title: | Development of high-rate timing RPCs | Authors: | Lopes, L. Marques, R. Ferreira Fonte, P. Pereira, A. Peskov, V. Policarpo, A. |
Keywords: | High-rate | Issue Date: | 2004 | Citation: | Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 533:1-2 (2004) 69-73 | Abstract: | 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/cm2 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/cm2 to 27 kHz/cm2. This result establishes the basic feasibility of timing measurements with RPCs at rates of tens of kHz/cm2, keeping a time resolution below 100 ps [sigma] and using plastic electrode materials. | URI: | https://hdl.handle.net/10316/4433 | DOI: | 10.1016/j.nima.2004.07.003 | Rights: | openAccess |
