摘要
致力于研究次级宇宙射线的极端能量事件（Extreme Energy Events, EEE）实验，可以说是世界上采用多气隙电阻板室（Multigap Resistive Plate Chambers, MRPC）实现的最大探测器系统。EEE 网络由分布在意大利全境的 60 台望远镜组成；每台望远镜由三个 MRPC 构成，能够以高效率与最佳角分辨率重建宇宙线粒子的轨迹。EEE 网络的一个显著特征是，几乎所有望远镜都安置在高中内，由学生和教师团队管理，他们此前曾在 CERN 参与其建造。这一特殊性对该实验是一大优势，使其将科学目标的相关性与有效的科普活动结合起来。探测器非传统的选址（主要位于学校建筑的标准教室内，维护条件各异，且无温控与专用供电线路）是验证 MRPC 技术在粒子监测与计时方面鲁棒性、低老化特性及持久性能的独特试验场。最后，报告了这些室的空间分辨率、效率、径迹重建能力及稳定性随时间的变化情况。
