论文摘要
CERN的大型强子对撞机(LHC)将进行重大升级,以将瞬时光度提高到5-7.5 $ \ times10^{34} $ cm $ $^{ - 2} $ s $ s $^{ - 1} $。 LHC(HL-LHC)的这种高光度升级将在13-14 TEV的质量中心能量中提供总计3000-4000 fb $^{ - 1} $的质子 - 质子碰撞。为了应对这些具有挑战性的环境条件,将使用带有两个紧密间隔硅传感器的模块来升级CMS实验的带状跟踪器,以提供信息,以在Level-1触发器选择中进行跟踪。本文在测试束实验中描述了第一个原型模块的性能,该模块基于CMS二进制芯片前端ASIC的最终版本,并在模块被中子辐照之前和之后的性能。结果表明,原型模块满足要求,提供有效的跟踪信息,在用实验生命周期中预期的总通量受到辐照后,可提供有效的跟踪信息。
The Large Hadron Collider (LHC) at CERN will undergo major upgrades to increase the instantaneous luminosity up to 5-7.5$\times10^{34}$ cm$^{-2}$s$^{-1}$. 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.
