在高亮度LHC时代，MIP定时探测器将为CMS的最小电离粒子（MIPs）检测提供额外的定时能力，改善事件重建和堆积抑制。探测器的中心部分，桶形定时层（BTL），将配备LYSO: Ce晶体和硅光电倍增管（SiPMs），在开始运行时提供约30 ps的时间分辨率，在探测器寿命结束时，由于辐射损坏，时间分辨率下降到50-60 ps。在这项工作中，我们介绍了在费米实验室测试光束设备上使用120 GeV质子束测量未辐照传感器时间分辨率的结果。演示了MTD筒状区域传感器布局的概念验证，该传感器布局由尺寸约为3× 3× 57 mm 3的细长晶棒组成，并具有双端SiPM读出器。这种设计提供了一个可靠的时间测量，与MIP沿晶棒的冲击点无关。我们测试了不同厚度（2,3,4 mm）的LYSO: Ce棒，其几何形状接近参考设计，并与Hamamatsu和Fondazione Bruno Kessler制造的SiPMs耦合。研究了晶体厚度、光子探测效率等特性以及MIP的冲击角等因素对同步性能的影响。通过3 mm厚的晶体条测量到的MIPs时间分辨率约为28 ps，对应于2.6 MeV能量沉积的最可能值（MPV），对应于BTL预期的4.2 MeV MPV能量沉积的22 ps，符合未辐照器件的探测器性能目标。
The MIP Timing Detector will provide additional timing capabilities for detection of minimum ionizing particles (MIPs) at CMS during the High Luminosity LHC era, improving event reconstruction and pileup rejection. The central portion of the detector, the Barrel Timing Layer (BTL), will be instrumented with LYSO: Ce crystals and Silicon Photomultipliers (SiPMs) providing a time resolution of about 30 ps at the beginning of operation, and degrading to 50-60 ps at the end of the detector lifetime as a result of radiation damage. In this work, we present the results obtained using a 120 GeV proton beam at the Fermilab Test Beam Facility to measure the time resolution of unirradiated sensors. A proof-of-concept of the sensor layout proposed for the barrel region of the MTD, consisting of elongated crystal bars with dimensions of about 3× 3× 57 mm 3 and with double-ended SiPM readout, is demonstrated. This design provides a robust time measurement independent of the impact point of the MIP along the crystal bar. We tested LYSO: Ce bars of different thickness (2, 3, 4 mm) with a geometry close to the reference design and coupled to SiPMs manufactured by Hamamatsu and Fondazione Bruno Kessler. The various aspects influencing the timing performance such as the crystal thickness, properties of the SiPMs (eg photon detection efficiency), and impact angle of the MIP are studied. A time resolution of about 28 ps is measured for MIPs crossing a 3 mm thick crystal bar, corresponding to a most probable value (MPV) of energy deposition of 2.6 MeV, and of 22 ps for the 4.2 MeV MPV energy deposition expected in the BTL, matching the detector performance target for unirradiated devices.
