论文摘要
为了在未来的高速压缩重型重质物质（CBM）实验中提供带电的HADRON的颗粒鉴定（PID），TOF组开发了一个大区域飞行时间（TOF）壁，配备了多间隙电阻板室（MRPC），可在入射粒子上运行，可在入射粒子上运行，最高30 kHz/cm $ $ $ $^2 $^2 $^2 $^2 $^2 $。在抗脂子和离子研究设施的注定操作之前 - 从2025年开始 - 这种高速计时MRPC技术将在公平阶段0计划的两个科学支柱上用于物理研究：RHIC的终端CAP TOF TOF TOF升级在RHIC和MCBM MCBM实验的MTOF Wall sis18 sis18。在Star，Beam Energy Scan II（BES-II）的固定目标程序将依靠108 CBM MRPC检测器以高达2 kHz的触发速率进行正向PID。在MCBM，在顶部SIS18 Energies处的Lambda-Baryon产生的高性能基准运行，CBM设计相互作用速率为10 MHz将变得可行，由25 CBM MRPC探测器组成的PID主链。从物理学的角度来看，这些事前的参与将有助于收集经验，以操作最终的CBM TOF墙，其中包括约1500个MRPC探测器和110,000个读取频道。将讨论公平阶段0计划的状态。
In order to provide particle identification (PID) of charged hadrons at the future high-rate Compressed Baryonic Matter (CBM) experiment the TOF group has developed a large-area Time-of-Flight (ToF) wall equipped with Multi-gap Resistive Plate Chambers (MRPC) capable to operate at incident particle fluxes of up to 30 kHz/cm$^2$. Prior to its destined operation at the Facility for Antiproton and Ion Research (FAIR) - starting in 2025 - this high-rate timing MRPC technology will be used for physics research at two scientific pillars of the FAIR Phase-0 program: the end-cap TOF upgrade of the STAR experiment at RHIC and the mTOF wall of the mCBM experiment at SIS18. At STAR, the fixed-target program of the Beam Energy Scan II (BES-II) will rely on 108 CBM MRPC detectors for forward PID at trigger rates of up to 2 kHz. At mCBM, high-performance benchmark runs of Lambda-baryon production at top SIS18 energies and CBM design interaction rates of 10 MHz will become feasible with a PID backbone consisting of 25 CBM MRPC detectors. Apart from the physics perspective, these pre-FAIR involvements will help gathering experience in operating the final CBM TOF wall comprising about 1500 MRPC detectors and 110,000 readout channels. The status of the FAIR phase 0 program will be discussed.
