One of the four key recommendations of the Nuclear Science Advisory Committee's 2015 Long Range Plan (LRP) included increasing investment in small-scale and mid-scale projects and initiatives that enable forefront research at universities and laboratories. The LRP also encourages education and workforce development as well as research and development into state-of-the-art tools and techniques for nuclear science. This project, the development of a particle physics detector at Chicago State University and California Polytechnic State University, will enable the transfer of knowledge from an international collaboration of world-class physicists and engineers at Europe's Large Hadron Collider (LHC) to our universities. This will provide unique opportunities to train undergraduate students in electronics, detection techniques, laser technology, data analysis, and instrumentation interface. The Fast Interaction Trigger Detector (FIT) proposed here is an instrument that meets specific requirements as the Minimum Bias trigger for one of the particle detector systems (called ALICE) at the LHC: (a) The capability to discriminate beam-beam interactions with a 99% efficiency for the collisions generated by the LHC at a rate of 50 kHz for Pb-Pb collisions and a rate of 200 kHz for p-p and p-Pb collisions. (b) The capability to provide a start signal for the rest of the ALICE detectors (Level 0 trigger) with a time resolution better than 30 ps. In addition to these design parameters, the FIT detector will provide the following measurements: (a) Charged particle multiplicity (b) Interaction reaction plane (c) First measurement of the collision vertex position. FIT will also be the key detector to provide direct feedback to the LHC. It will be the first of the ALICE detectors to be turned on to perform beam tuning and monitor online luminosity. These characteristics, not available in any instrument provided by a vendor, require the development of a unique instrument at the vanguard of trigger detectors for high energy nuclear and particle physics.

核科学咨询委员会 2015 年长期计划 (LRP) 的四项关键建议之一包括增加对中小型项目和倡议的投资，以促进大学和实验室的前沿研究。 LRP 还鼓励教育和劳动力发展以及最先进的核科学工具和技术的研究和开发。该项目是芝加哥州立大学和加州理工州立大学粒子物理探测器的开发项目，将使欧洲大型强子对撞机 (LHC) 世界级物理学家和工程师的国际合作知识转移到我们的大学。这将为在电子学、检测技术、激光技术、数据分析和仪器接口方面培训本科生提供独特的机会。这里提出的快速交互触发探测器 (FIT) 是一种满足 LHC 粒子探测器系统（称为 ALICE）之一的最小偏置触发器特定要求的仪器： LHC 在 Pb-Pb 碰撞速率为 50 kHz 以及 p-p 和 p-Pb 碰撞速率为 200 kHz 时产生的碰撞效率为 99%。 (b) 能够为其余 ALICE 探测器（0 级触发器）提供时间分辨率优于 30 ps 的启动信号。除了这些设计参数之外，FIT 探测器还将提供以下测量值： (a) 带电粒子多重性 (b) 相互作用反应平面 (c) 碰撞顶点位置的首次测量。 FIT也将成为向大型强子对撞机提供直接反馈的关键探测器。它将是第一个被打开来执行光束调谐和监测在线光度的 ALICE 探测器。这些特性是供应商提供的任何仪器所不具备的，因此需要开发一种独特的仪器，作为高能核和粒子物理触发探测器的先锋。
