具有几十微米的位置精度和接近MHzmm−2的速度能力，使用气体电子倍增器(GEM)作为放大元件的探测器在需要精确了解能量损失拓扑结构时很有吸引力。此外，它们坚固耐用，易于制造。级联两个或多个宝石箔允许在恶劣的操作条件下实现更大的收益和可靠的运行。我们讨论了新器件的工作原理和主要性能，特别是考虑到它们可能用于跃迁辐射和切伦科夫环成像探测器中的粒子识别。
Offering position accuracies of few tens of microns and rate capabilities close to a MHzmm−2, detectors using the Gas Electron Multiplier (GEM) as amplifying element are attractive whenever a precise knowledge of the energy loss topology is required. Moreover, they are robust and easy to manufacture. Cascading two or more GEM foils permits to achieve larger gains and reliable operation in harsh operating conditions. We discuss the operating principles and the major performances of the new devices, particularly in view of their possible use for particle identification in Transition Radiation and Cherenkov ring imaging detectors.
