摘要
极端能量事件（EEE）项目采用多气隙电阻板室（MRPC）研究广延空气簇射中的次级宇宙线缪子。该阵列由约 60 台追踪探测器组成，分散分布于意大利境内及 CERN。MRPC 通以基于 和 的气体混合物，二者均为含氟温室气体，对大气具有高度环境影响。由于欧盟施加的限制，这些气体正逐步停产且成本大幅上升。EEE 合作组发起了一项减少其阵列气体排放的 campaign，旨在控制成本并降低实验的全球变暖影响。一种方法是降低每台 EEE 探测器的气体流速。另一种是开发气体再循环系统，其首个原型已安装于 CERN 的一处 EEE 站点。同时，一项并行策略聚焦于寻找不影响 MRPC 性能且能替代标准混合气体的环境友好型气体混合物。本文给出概述与初步结果。
