Performance of the BIS78 RPC detectors: a new concept of electronics and detector integration for high-rate and fast timing large size RPCs

摘要:

气体中每计数的平均电荷的减少以及区分非常小的信号与噪声的能力可以允许在高辐射背景环境中进行有效和长期的电阻板室检测器操作。这一目标已经达到了在研究与发展计划的BIS 78升级项目的ATLAS探测器在LHC通过深度集成的快速(100 ps的峰值时间)和敏感(小至100 V的阈值)前端电子(FE)与一个非常大的尺寸的检测器结构。这种创新的RPC集成概念以新构思的法拉第笼为中心,将读出条和FE嵌入其中,紧紧包裹在具有1.2 mm厚电极的1 mm气隙RPC周围,作为完全独立的单线态结构。我们研究了BIS 78生产三重腔室的性能,该三重腔室由3个2 <2的独立单重态组成,每个单重态提供2D空间和时间信息,显示出可实现的最小阈值为在气隙内产生的每计数2 pC的平均电荷。我们表明,这些商会授予一个记录的综合性能更好

英文摘要:

The reduction of the average charge per count in the gas along with the capability to discriminate very small signals from noise can allow an efficient and long-term Resistive Plate Chamber detector operation in high radiation background environment. This goal has been reached during the R&D program of the BIS78 upgrade project of the ATLAS detector at LHC through the deep integration of a fast (100 ps peaking time) and sensitive (as small as 100 `V threshold) Front- End electronics (FE) with a very large size detector structure. This innovative RPC integration concept pivots on a newly conceived faraday cage, embedding the readout strips and the FE, tightly wrapped around a 1 mm gas gap RPC with 1.2 mm thick electrodes, as a fully independent singlet structure. We studied the performance of BIS78 production triplet chambers, made of 3 independent singlets of 2 <2, each providing a 2D space and time information, showing a minimum threshold achievable of 2 pC of average charge per count produced inside the gas gap. We show that these chambers grant a record combined performance of better
