Developing the Track Finder and associated electronics for the upgrade of the CMS detector for the High Luminosity LHC

在可预见的未来，欧洲核子研究中心的大型强子对撞机（LHC）将是世界上能量最高的粒子加速器，也是唯一能够研究基础物理学中一些最优先主题的设备。大型强子对撞机的运行将至少持续到2035年，为了提供有用的统计范围和相关探测器，对加速器综合体的性能要求不断提高。因此，CMS探测器需要进行重大和全面的升级，以便在更恶劣的条件下保持性能。英国在跟踪系统、末端热量计和触发系统升级的关键方面处于领先地位。共同的元素是高通量数字电子的发展，以及它们对上述三个特定子系统的定制。David的博士学位专注于跟踪系统的开发，特别是跟踪触发器和相关的“设计，触发和控制”板。这项工作包括开发功能强大的软件和固件，以及改进寻迹和电子识别的算法，以及在欧洲核子研究中心对整个系统的各个部分进行集成测试。David将需要设计和构建适当的测试设置。

The Large Hadron Collider (LHC) at CERN will be the world's highest energy particle accelerator for the foreseeable future, and the only facility capable of investigating some of the highest priority topics in fundamental physics. LHC operation will continue until at least 2035, with ever-increasing performance required from the accelerator complex in order to provide useful statistical reach and from the associated detectors. As such the CMS detector will require significant and comprehensive upgrades in order to maintain performance in the presence of much harsher conditions. The UK is leading key aspects of the upgrades to the tracking system, end-cap calorimeters and the trigger system. The common element is the development of high throughput digital electronics, and their tailoring to the three specific sub-systems mentioned above. David's PhD is focused on developments for the tracking system, and in particular for the Track Trigger and the associated 'Design, Trigger and Control' board. The work involves developing suitably powerful software and firmware, as well as algorithmic improvements to the track finding and electron identification, as well as integration tests of parts of the overall system at CERN. David will need to design and build the appropriate test set-ups.
