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，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非常具有挑战性。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。由于实验体积大，带电轨迹在高磁场中弯曲时需要重建，因此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。虽然我们知道如何用硅来做到这一点，并且大型强子对撞机实验ATLAS和CMS分别有60平方米和200平方米面积的硅跟踪器，但我们不知道如何在这些区域建立适合10倍于LHC预期剂量的阵列。这正是超级强子对撞机的要求，它的平均碰撞率将是大型强子对撞机的十倍。该提案是一种新颖的方法，可以以经济实惠的方式建造探测器，从而满足这些需求。它建立在利物浦制造能够应对这些非常高剂量的小型探测器系统的经验基础上，并提出探索e2v为其他辐射环境开发的处理技巧，以提出一种强大的方法来制造SLHC所需的大量硅微带探测器。请注意：我们试图提交一份联合提案，指定e2v为牵头机构。然而，由于e2v不会使用JeS系统输入，这似乎不被接受。这已经报告给了JeS (RE：可能的技术困难与行业让加入投标- HA207389)，他们确认系统不允许这样做。因此，我们希望确保STFC理解这是一个e2v led投标，尽管这必须输入到JeS，以便电子系统接受申请。
