摘要:

电阻板室的固有速率能力和老化特性与电极材料和前端电子学阈值密切相关。低噪声前置放大器的开发使我们将高压层压板(酚醛树脂)的固有速率能力提高到$\sim10\;kHz/cm^2$,然而有效速率受到电极老化的显著限制。为了进一步提高有效倍率性能,研究了新材料。具有晶体半绝缘砷化镓电极的电阻板室已经在束测试设备(BFT)(意大利弗拉斯卡蒂的INFN国家实验室)用高能电子束表征。在雪崩模式下操作检测器,测量电阻板室对多个聚束电子的响应。在GIF++设施(SPS的EHN 1,CERN)的均匀高能γ辐射场中操作探测器也测量了固有速率能力。

英文摘要:

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).
