本文描述了用于测量大型强子对撞机中心衍射相互作用中产生的质子的飞行时间(TOF)的计时探测器的设计和性能。通过测量质子的飞行时间，可以确定质子相互作用顶点的纵向位置及其与由CMS探测器重建的顶点之一的关联。TOF探测器基于单晶化学气相沉积(ScCVD)金刚石板，设计用于测量质子TOF，时间精度约为50ps。这次对图腾装置的升级将用于LHC RUN 2，并将标记中心衍射事件，最高相互作用堆积约为1。已经开发了用于信号放大的专用快速和低噪声电子设备。通过对波形进行采样来执行钻石信号的数字化。在介绍了将从这些新探测器的添加中获益最大的物理研究之后，我们详细讨论了2015年11月安装在大型强子对撞机上的第一个TOF探测器的优化和性能。
This paper describes the design and the performance of the timing detector developed by the TOTEM Collaboration for the Roman Pots (RPs) to measure the Time-Of-Flight (TOF) of the protons produced in central diffractive interactions at the LHC . The measurement of the TOF of the protons allows the determination of the longitudinal position of the proton interaction vertex and its association with one of the vertices reconstructed by the CMS detectors. The TOF detector is based on single crystal Chemical Vapor Deposition (scCVD) diamond plates and is designed to measure the protons TOF with about 50 ps time precision. This upgrade to the TOTEM apparatus will be used in the LHC run 2 and will tag the central diffractive events up to an interaction pileup of about 1. A dedicated fast and low noise electronics for the signal amplification has been developed. The digitization of the diamond signal is performed by sampling the waveform. After introducing the physics studies that will most profit from the addition of these new detectors, we discuss in detail the optimization and the performance of the first TOF detector installed in the LHC in November 2015.
