论文摘要
这项工作是提出和探索多通道读数电子产品的使用，该电子设备已经用于质量保证，用于增益均匀性研究，以测量基于GEM的检测器中诱导间隙的均匀性。该测量将根据断开或缩短的通道提供读数电极的资格。所提出的方法依赖于对读数条和宝石底部之间的感应间隙电容的依赖。该测量是在启动的读数条上诱导信号的，旋转了宝石箔的底层。在这项工作中，使用模拟APV25前端芯片和RD51可扩展读数系统（SRS）读取信号。将显示有关小面积GEM探测器，机械应力下的相对变化以及在存在电场的研究。将证明对读数平面缺陷的敏感性。
This work is proposing and exploring the use of multichannel readout electronics, already used in quality assurance for gain uniformity studies, to measure the uniformity of the induction gap in GEM based detectors. The measurement will furthermore provide a qualification of the readout electrodes in terms of disconnected or shorted channels. The proposed method relies on the dependence on the induction gap capacitance between the readout strips and the bottom of the GEM. The measurement is obtained inducing capacitively a signal on the readout strips pulsing the bottom layer of the GEM foil. In this work, the signals are read with the analog APV25 front-end chip and the RD51 Scalable Readout System (SRS). Studies on small and large area GEM detectors, relative variations under mechanical stress, and in presence of electrical fields will be shown. Sensitivity to defects in the readout plane will be proven.
