论文摘要
带电线（WGEM）或金属电极（MGEM）的气体电子乘数（GEMS），它们不会在电极之间使用任何塑料绝缘子。 WGEM电极之间没有塑料绝缘材料不包括不需要的泄漏电流和电极之间的火花故障。这种MGEM中的意外火花事件不会导致其失败，因为正离子迅速通过差距区域的强烈电场从崩溃区域移开。在这项工作中，我们介绍了此类宝石的评论。提出了含有销钉轴的MGEM（WGEM）的腔室作为检测器，以搜索暗物质颗粒与氢之间的相互作用（H2）。在本文中，我们介绍了此类房间的评论。为了研究气体混合物（AR+10％H2，NE+10％H2，H2+3PPMTMAE），构建了含有带PIN-动臂检测系统的WGEM的腔室。在本文中，我们介绍了由Alpha源退出的这些气体混合物的实验研究结果。最后，我们讨论了带有销钉轴的宝石的操作原理，以及构建大规模（150 mm x 150 mm）MGEM探测器的计划。
Gas electron multipliers (GEMs) with wire (WGEMs) or metal electrodes (MGEMs), which don't use any plastic insulators between the electrodes are created. The absence of plastic insulation between the electrodes of WGEMs excludes unwanted leakage currents and spark breakdowns between the electrodes. Accidental spark events in such MGEM don't lead to their failure as far as positive ions quickly move away from the breakdown region by a strong electric field in the gap region. In this work, we present a review of such GEMs. The chambers containing MGEMs (WGEMs) with pin-anodes are proposed as detectors for searching of interactions between Dark Matter particles and hydrogen (H2). In this paper, we present a review of such chambers. For investigation of the gas mixtures (Ar+10% H2, Ne+10%H2, H2 +3ppmTMAE), the chamber containing WGEM with pin-anodes detection system was constructed. In this paper we present the results of an experimental study of these gaseous mixtures exited by an alpha source. Finally, we discuss principles of operation of GEMs with pin-anodes as well as plans for constructing of large scale (150 mm x 150 mm) MGEM detectors.
