项目摘要

Detectors needed by particle physics experiments have to withstand huge radiation doses and work for many years. As accelerators become able to reach higher energies and create more and more collisions per second, the requirements for detectors to survive inside the experiments becomes highly challenging. At the moment, the best option for high speed, radiation hard position sensitive detectors is to use segmented silicon. For the volume of the experiment where charged tracks need to be reconstructed as they bend in a high magnetic field, large areas of detectors measuring the particle trajectories to hundredth of a millimeter precision are needed. While we know how to do this with silicon and the LHC experiments ATLAS and CMS have silicon trackers of 60m2 and 200m2 area respectively, we do not know how to build arrays of these areas suitable for ten times the expected dose at the LHC. This is exactly the requirement of the Super-LHC which will operate with an average collision rate ten times that of the LHC. The proposal is a novel approach to building detectors affordably that can meet these demands. It builds on experience at Liverpool in making smaller detector systems able to cope with these very high doses and proposes to explore processing tricks developed for other radiation environments by e2v to come up with a robust method for making the large quantities of silicon microstrip detectors required for the SLHC. Please note: We have tried to put in a joint proposal specifying that e2v are the lead institute. However, since e2v will not input using the JeS system, this seems not to be accepted. This has been reported to JeS (RE: Possible technical difficulties with industry let join bids - HA207389) and they confirmed the system does not allow this. Therefore, we want to make sure STFC understand this is an e2v led bid despite the way this has to be input to JeS so that the electronic system will accept the application.

粒子物理实验所需的探测器必须能够承受巨大的辐射剂量并工作多年。随着加速器能够达到更高的能量并每秒产生越来越多的碰撞，探测器在实验中生存的要求变得极具挑战性。目前，高速、辐射硬位置敏感探测器的最佳选择是使用分段硅。对于需要在高磁场中弯曲时重建带电轨道的实验量，需要大面积的探测器来测量粒子轨迹，精度达到百分之一毫米。虽然我们知道如何使用硅来做到这一点，并且大型强子对撞机实验 ATLAS 和 CMS 分别拥有面积为 60 平方米和 200 平方米的硅跟踪器，但我们不知道如何构建这些区域的阵列，以适应大型强子对撞机预期剂量的十倍。这正是超级大型强子对撞机的要求，超级大型强子对撞机的平均碰撞率是大型强子对撞机的十倍。该提案是一种以经济实惠的方式构建能够满足这些需求的探测器的新颖方法。它借鉴了利物浦在制造能够应对这些非常高剂量的小型探测器系统方面的经验，并建议探索 e2v 为其他辐射环境开发的处理技巧，以提出一种稳健的方法来制造所需的大量硅微带探测器。 SLHC。请注意：我们已尝试提出一份联合提案，指定 e2v 为牵头机构。然而，由于e2v不会使用JeS系统输入，因此这似乎不被接受。这已报告给 JeS（回复：行业可能存在技术困难，让我们加入投标 - HA207389），他们确认系统不允许这样做。因此，我们希望确保 STFC 明白这是一个 e2v 主导的投标，尽管必须将其输入 JeS 以便电子系统接受申请。
