Precision Mechanical Detector Assemblies for Particle Physics

根据粒子物理学的标准模型，宇宙是由少数基本粒子组成的，受几种基本力的支配。为了研究基本粒子的物理学，在对撞机实验中再现了宇宙诞生之初的状态：欧洲核子研究中心的大型强子对撞机（LHC）于2010年开始收集数据，这是一个粒子加速器，比以往任何时候都能更深入地探索大爆炸的过程。它最终将以14 TeV的能量碰撞质子束，这相当于一个只有几分之一秒年龄的婴儿宇宙。由几个不同组件组成的大型探测器将探测到碰撞光束产生的衰变产物。来自所有探测器元素的信息集合用于重建碰撞中发生的情况。LHC升级为High Luminosity LHC （HL-LHC）以及未来计划的未来圆形对撞机（future Circular collider）等对撞机将通过强化对撞束来提高灵敏度。这也对探测器元件提出了新的挑战，以承受增加的辐射水平。拟议的项目将提升我们的计量能力，扩大我们的能力，以建立更高的精度和更大的面积探测器设备。这将使我们能够实施质量控制和质量保证，以生产下一代粒子跟踪探测器所需的精密机械探测器组件，这些探测器将用于大型强子对撞机和欧洲核子研究中心的实验。

According to the Standard Model of particle physics, the universe is made up from a small number of elementary particles, governed by a few fundamental forces. To study the physics of elementary particles the conditions which governed the universe at its beginning are reproduced in collider experiments: The Large Hadron Collider (LHC) at CERN started to collect data in 2010, a particle accelerator which probes deeper into the processes of the Big Bang than ever before. It will ultimately collide beams of protons at an energy of 14 TeV, which corresponds to an infant universe of only a fraction of a second in age. Large detectors with several different components will detect the decay products emerging from the colliding beams. The ensemble of information from all detector elements is used to reconstruct what happened in the collision. The upgrade of LHC to the High Luminosity LHC (HL-LHC) and future projected collider like the Future Circular Collider will boost the sensitivity by intensifying the colliding beams. This also poses new challenges to the detector elements to withstand the increased radiation levels. The proposed project will upgrade our metrology capabilities to expand our capabilities to build greater precision and larger-area detector devices. This will enable us the implement the quality control and quality assurance needed to produce precision mechanical detector assemblies for the next generation of particle tracking detectors, that will be used in the experiments at the Large Hadron Collider and beyond at CERN.
