SHiP (Search for Hidden Particles) is a general-purpose experiment to be installed in a new beam-dump facility at the SPS at CERN to search for hidden particles as predicted by a very large number of recently elaborated models. The proposed experimental apparatus contains, among others, a 50 m 2 Timing Detector, crucial to reject the combinatorial background, with a requirement of a timing precision better than 100 ps together with the highest possible detection efficiency. One possibility for the construction of the Timing Detector is the Multigap Resistive Plate Chamber (MRPC) technology. In this paper, we report the design and test beam results of the first full-scale module, based on a novel concept on the construction of MRPCs, where the glass stack and high-voltage electrodes are confined within a permanently sealed plastic box, exhibiting a time precision of 54 ps together with a detection efficiency of 98% over almost 2 m 2 ...

基于MRPC的SHiP时序检测器

SHiP（搜索隐藏粒子）是一项通用实验，将安装在CERN SPS的新束流转储设备中，以搜索大量近期精心设计的模型所预测的隐藏粒子。拟议的实验设备包括一个50 m 2的定时检测器，这对于拒绝组合背景至关重要，它要求定时精度要优于100 ps，并具有最高的检测效率。构造定时检测器的一种可能性是多间隙电阻板腔（MRPC）技术。在本文中，我们基于MRPC构造的新颖概念，报告了第一个满量程模块的设计和测试光束结果，其中，玻璃堆和高压电极被限制在永久密封的塑料盒中，
