亚25皮秒精度的带电粒子计时:PICOSEC探测概念

仪器与探测器 2019-07-24 v2

摘要

PICOSEC探测概念由耦合到切伦科夫辐射体并配备光阴极的“两级”Micromegas探测器构成。已对其原理进行验证:在CEA/IRAMIS利用飞秒紫外激光测得单光电子响应为76 ps,而在CERN SPS H4次级束线上对150 GeV缪子测得时间分辨为24 ps,平均产额为10.4个光电子。本文介绍该原型的主要结果以及2016-18年束流实验中所测试不同探测器构型的性能:读出(体式、电阻式、多焊盘)与光阴极(金属+CsI、纯金属、金刚石)。最后,将讨论基于PICOSEC探测概念为未来实验构建演示器的前景,特别是大面积覆盖的多通道读出平面的扩展策略、用于构建稳健光阴极的固态转换器研发,以及用于稳健读出的不同电阻构型。
