对欧洲核子研究中心罗盘实验高强度束附近区域的粒子的跟踪是基于两种新型的微图案气体探测器，Micromegas和GEM。由于其高定位精度和速率能力而被选中，这是这项高颗粒气体设备技术的固有特性，其高达40×40 cm2的大有效面积和较小的材料预算为高光度实验中的粒子跟踪提供了额外的优势。文中介绍了这些探测器的基本原理以及罗盘实验所采用的设计，目的是根据它们在光谱仪中的位置来优化操作。讨论了对两种类型的探测器实施的最小化气体排放概率并减少其对探测器操作的影响的方法。在2001年的指南针运行中，安装和成功运行的探测器总数占全部安装所需探测器总数的50%以上。首先，给出了有关COMPASS介子束工作特性的结果。
The tracking of particles in the region close to the high-intensity beam of the COMPASS experiment at CERN is based on two novel types of micropattern gaseous detectors, the Micromegas and the GEM. Chosen for their high localization accuracy and rate capability, intrinsic to this technology of highly granular gaseous devices, their large active area of up to 40×40 cm2and small material budget offer additional advantages for tracking of particles in a high-luminosity experiment. The basic principles of these detectors as well as the design adopted for the COMPASS experiment, aiming at optimization of operation according to their positions in the spectrometer, are presented. Means to minimize the probability of gas discharges, and to reduce their impact on detector operation, as implemented for both detector types, are discussed. For the 2001 run of COMPASS, over 50% of the total number of detectors required for the full setup was installed and successfully operated. First results concerning the operational characteristics in the COMPASS muon beam are presented.
