摘要:

我们报告的微通道板(MCP)对单个相对论粒子和电磁簇射的响应。通过MCP表面处的电子的二次发射的粒子探测早已被提出,并且被广泛用于离子飞行时间质谱仪中。尚未深入研究的是它们用于检测簇射的电离成分。MCP的时间分辨率超过了以前在量热计中使用的任何东西,如果有效利用,可以帮助在高亮度对撞机上重建事件。在INFN-LNF束流测试设施中,几个基于MCP的放大级光电探测器原型暴露于宇宙射线和491 MeV电子。测量的时间分辨率和效率的MCP的粒子多重性的函数,和用于模拟响应的结果,以高能量的淋浴。

英文摘要:

We report on the response of microchannel plates (MCPs) to single relativistic particles and to electromagnetic showers. Particle detection by means of secondary emission of electrons at the MCP surface has long been proposed and is used extensively in ion time-of-flight mass spectrometers. What has not been investigated in depth is their use to detect the ionizing component of showers. The time resolution of MCPs exceeds anything that has been previously used in calorimeters and, if exploited effectively, could aid in the event reconstruction at high luminosity colliders. Several prototypes of photodetectors with the amplification stage based on MCPs were exposed to cosmic rays and to 491 MeV electrons at the INFN-LNF Beam-Test Facility. The time resolution and the efficiency of the MCPs are measured as a function of the particle multiplicity, and the results used to model the response to high-energy showers.
