使用商业制造的大GEM箔构造三重GEM探测器
Construction of a Triple-GEM Detector Using Commercially Manufactured Large GEM Foils
摘要：
许多实验目前正在使用或提议在其检测器中使用大面积GEM箔，这产生了对商业上可获得的GEM箔的需求。目前，CERN是大型GEM箔的唯一主要分销商，但随着对GEM技术的兴趣越来越大，跟上对GEM日益增长的需求将是困难的。我们在这里提出了一个更新的组装和测试的三重GEM跟踪探测器利用单屏蔽$40 \times 40$ cm $^2$商业GEM箔生产的技术蚀刻。三重GEM探测器将使我们能够通过增益，效率和能量分辨率测量来表征这些Tech-Etch箔的整体质量。这将通过使用Tech-Etch制造的箔构建四个单掩模三GEM探测器来实现，这些箔遵循STAR Forward GEM Tracker（FGT）使用的设计。通过将箔胶合到框架上然后将框架胶合在一起来形成堆叠。该叠层还包括Tech-Etch生产的高压箔和2D $r-ϕ$读出箔。虽然四个三重GEM探测器中的一个将与STAR FGT相同，但其他三个将研究如何通过采用穿孔Kapton间隔环而不是G10间隔网格来进一步减少材料预算并提高探测器的效率，以减少探测器的死区。
英文摘要：
Many experiments are currently using or proposing to use large area GEM foils in their detectors, which is creating a need for commercially available GEM foils. Currently CERN is the only main distributor of large GEM foils, however with the growing interest in GEM technology keeping up with the increasing demand for GEMs will be difficult. We present here an update on the assembly and testing of triple-GEM tracking detectors utilizing single-masked $40 \times 40$ cm$^2$ commercial GEM foils produced by Tech-Etch. The triple-GEM detectors will allow us to characterize the overall quality of these Tech-Etch foils through gain, efficiency, and energy resolution measurements. This will be done by constructing four single-mask triple-GEM detectors, using foils manufactured by Tech-Etch, which follow the design used by the STAR Forward GEM Tracker (FGT). The stack is formed by gluing the foils to the frames and then gluing the frames together. The stack also includes a Tech-Etch produced high voltage foil and a 2D $r-ϕ$ readout foil. While one of the four triple-GEM detectors will be built identically to the STAR FGT, the other three will investigate ways in which to further decrease the material budget and increase the efficiency of the detector by incorporating perforated Kapton spacer rings rather than G10 spacing grids to reduce the dead area of the detector.
