GEM探测器可以在各种高能和核物理实验中作为高精度跟踪探测器。然而，相对论重离子实验不仅可能提供非常高的轨道多重性，而且还可能为GEM探测器的操作提供严格的背景条件。为了研究它们在这些条件下的使用，在RHIC的PHENIX实验中对三级GEM探测器进行了测试。探测器被放置在PHENIX中心光谱仪内部靠近碰撞点的区域，并在全光度金-金碰撞期间运行。给出了在氩气/CO/sub - 2/和纯CF/sub - 4/两种气体混合物下，探测器的工作稳定性和对光束相关背景的灵敏度。
GEM detectors can serve as high precision tracking detectors in a variety of high energy and nuclear physics experiments. However, relativistic heavy ion experiments can potentially provide not only very high track multiplicities, but also severe background conditions for operating GEM detectors. To study their use under these conditions, a test was carried out of a three stage GEM detector in the PHENIX experiment at RHIC. The detector was placed in a region close to the collision point inside the PHENIX central spectrometer and operated during full luminosity gold-gold collisions. Results are given on the stability of operation and the sensitivity of the detector to beam related backgrounds using both argon/CO/sub 2/ and pure CF/sub 4/ gas mixtures.
