摘要:

在未来的强子对撞机上,预期每个束团交叉会发生数百次并发碰撞。精确定时量热法一直被提倡作为一种减轻堆积效应的方法,并且由于其出色的时间分辨率,微通道板(MCP)是实现这一目标的良好候选检测器。我们报告的MCP,用作二次发射探测器,单一相对论粒子和电磁簇射的响应。几个原型,具有不同的几何形状和特性,暴露于粒子束在INFN-LNF束流测试设施和欧洲核子研究中心。它们的时间分辨率和效率测量为单个粒子和作为粒子的多重性的函数。对单个相对论性粒子的影响在50%到90%之间,而在大量粒子的存在下,则高达100%。时间分辨率在20 ps ~ 30 ps之间。

英文摘要:

Hundreds of concurrent collisions per bunch crossing are expected at future hadron colliders. Precision timing calorimetry has been advocated as a way to mitigate the pileup effects and, thanks to their excellent time resolution, microchannel plates (MCPs) are good candidate detectors for this goal. We report on the response of MCPs, used as secondary emission detectors, to single relativistic particles and to electromagnetic showers. Several prototypes, with different geometries and characteristics, were exposed to particle beams at the INFN-LNF Beam Test Facility and at CERN. Their time resolution and efficiency are measured for single particles and as a function of the multiplicity of particles. Efficiencies between 50% and 90% to single relativistic particles are reached, and up to 100% in presence of a large number of particles. Time resolutions between 20ps and 30ps are obtained.
