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年远程计划（LRP）的四个关键建议之一包括增加对中小型和中期项目的投资以及使大学和实验室实现前列研究的计划。 LRP还鼓励教育和劳动力发展以及对核科学最先进的工具和技术的研发。该项目是芝加哥州立大学和加利福尼亚理工大学粒子物理探测器的开发，将使知识从国际合作的世界一流的物理学家和工程师的国际合作转移到欧洲大型强子撞机（LHC）到我们的大学。这将为培训本科生的电子，检测技术，激光技术，数据分析和仪器界面提供独特的机会。 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）为其余的爱丽丝探测器（0级触发器）提供的起始信号，其时间分辨率优于30 ps。除这些设计参数外，拟合检测器还将提供以下测量值：（a）带电的粒子多样性（b）相互作用反应平面（c）碰撞顶点位置的首次测量。 FIT也将是向LHC提供直接反馈的关键检测器。这将是第一个打开的爱丽丝探测器，以执行梁调整并监视在线亮度。这些特征在供应商提供的任何仪器中都不可用，都需要在触发探测器的先锋仪中开发出独特的仪器，以进行高能核和粒子物理。
