论文摘要
电阻板室的内在速率能力和老化特性与电极材料和前端电子阈值密切相关。低噪声前放大器的发展使我们提高了高压层压板（Bakelite）的内在速率能力，最高为$ \ sim10 \; khz/cm^2 $，但是，电极衰老的有效速率受到了显着限制。为了进一步提高有效速率能力，研究了新材料。具有结晶半胰岛砷烯化电极的电阻板室已在梁测试设施（BFT）（意大利Frascati国家实验室）的高能电子束进行表征。在雪崩模式下测量了电阻板室对多束电子的响应。还测量了在GIF ++设施（SPS，CERN的EHN1）的均匀高能辐射场中运行检测器的内在速率能力。
The intrinsic rate capability and the ageing properties of the Resistive Plate Chambers are closely related to the electrodes material and to the front-end electronics threshold. The development of a low noise pre-amplifier led us to improve the intrinsic rate capability of High Pressure Laminate (bakelite) up to $\sim10\;kHz/cm^2$, nevertheless the effective rate is significantly limited by electrodes ageing. To further improve the effective rate capability new materials are investigated. A Resistive Plate Chamber with crystalline semi-insulating Gallium Arsenide electrodes has been characterized with high energy electrons beam at the Beam Test Facility (BFT), (INFN National Laboratory of Frascati, Italy). The response of the Resistive Plate Chamber to multiple bunched electrons was measured operating the detector in avalanche mode. The intrinsic rate capability has been also measured operating the detector in a uniform high energy gamma radiation field at the GIF++ facility (EHN1 of SPS, CERN).
