欧洲核子研究中心（CERN）的大型强子对撞机（LHC）将进行重大升级，将瞬时光度提高到5-7.5×1034 cm-2s-1。这种高亮度升级的LHC （HL-LHC）将在13-14 TeV的质心能量下提供总计3000-4000 lb -1的质子-质子碰撞。为了应对这些具有挑战性的环境条件，CMS实验的条形跟踪器将使用两个紧密间隔的硅传感器模块进行升级，以提供信息，包括1级触发选择中的跟踪。本文描述了基于CMS二进制芯片前端ASIC最终版本的第一个原型模块在中子辐照前后的测试束流实验的性能。结果表明，原型模块满足要求，提供了有效的跟踪信息，辐照后的总影响与实验生命周期内的预期影响相当。
The Large Hadron Collider (LHC) at CERN will undergo major upgrades to increase the instantaneous luminosity up to 5–7.5×1034 cm-2s-1. This High Luminosity upgrade of the LHC (HL-LHC) will deliver a total of 3000–4000 fb-1 of proton-proton collisions at a center-of-mass energy of 13–14 TeV. To cope with these challenging environmental conditions, the strip tracker of the CMS experiment will be upgraded using modules with two closely-spaced silicon sensors to provide information to include tracking in the Level-1 trigger selection. This paper describes the performance, in a test beam experiment, of the first prototype module based on the final version of the CMS Binary Chip front-end ASIC before and after the module was irradiated with neutrons. Results demonstrate that the prototype module satisfies the requirements, providing efficient tracking information, after being irradiated with a total fluence comparable to the one expected through the lifetime of the experiment.
