项目摘要

Over the last 25 years, silicon sensor technology has become a critical ingredient in the success of the most challenging experiments in fundamental physics. The discovery of the Higgs boson at the Large Hadron Collider (LHC), most notably, would not have been possible without the very fine grained sensors which sit at the heart of the CERN detectors to measure (track) the trajectories of thousands of particles produced tens of millions of times per second. The next generation of experiments, being planned today, relies on a step-change in the performance of tracking sensor technologies. Scientists seek detectors that provide micron scale position accuracy and better than one nanosecond timing resolution, while being substantially thinner than a sheet of paper and requiring little cooling. To date it has not been possible to combine all of them in a single device.In this research, I propose to develop novel Depleted Monolithic Active Pixel Sensors (DMAPS) to achieve these parameters in a single device using industry standard, and therefore cost-effective, High Voltage-Complementary Metal-Oxide-Semiconductor (HV-CMOS) processes. DMAPS have already been adopted as the chosen sensor technology for the Mu3e experiment at the Paul Scherrer Institute in Switzerland, for which I work on the construction of the first DMAPS pixel tracker that will come online in 2020. DMAPS are also developed for the planned phase-II upgrade of ATLAS at the LHC, for which the final technology decision is expected in 2019. Within the particle physics instrumentation community, there is now a wide consensus that DMAPS will replace traditional tracking sensor technologies in the next generation of particle physics experiments.In spite of the major improvements already demonstrated by DMAPS, the enormous challenges set by future particle physics experiments demand further research to achieve yet more performant sensors. The main goal of this research is to develop highly performant DMAPS, targeting in the first place the reduction of the pixel area, the improvement of the time resolution and the increase of the radiation tolerance. I will also develop full-size DMAPS detectors with optimised performance and pursue the deployment of these devices for particle physics experiments and beyond. These new detectors can have a massive impact in experiments such as a planned upgrade of Mu3e and future upgrades at the High Luminosity-LHC (HL-LHC), but also in the medical and commercial fields as the low cost typical of HV-CMOS processes will make DMAPS tracking detectors available to many.

在过去的25年中，硅传感器技术已成为基本物理最具挑战性实验的成功的关键要素。如果没有非常细的谷物传感器位于CERN探测器的心脏地点以测量（轨迹）产生的数千个颗粒的轨迹，那么在大型强子对撞机（LHC）处发现了Higgs玻色子是不可能的。每秒数千万次。下一代的实验（如今已计划）依赖于跟踪传感器技术的性能的逐步变化。科学家寻求提供微米尺度位置精度的探测器，并且比一个纳秒时序分辨率更好，同时比一张纸要薄得多，几乎不需要冷却。到目前有效的高电压平衡金属 - 氧化物 - 氧化物 - 氧化物 - CMOS过程。 DMAP已被用作瑞士Paul Scherrer Institute的MU3E实验的选定传感器技术，为此，我为2020年在线上线的第一个DMAPS Pixel Tracker的构建。 -II在LHC上的ATLA升级，预计在2019年将在2019年进行最终技术决策。在粒子物理仪器社区中，现在有一个广泛的共识，即DMAP将取代下一代粒子物理实验中传统的跟踪传感器技术。尽管DMAP已经证明了重大改进，但未来粒子物理实验设定的巨大挑战需要进一步的研究以实现更多的性能传感器。这项研究的主要目标是开发高性能的DMAP，首先是针对像素区域的减少，时间分辨率的改善和辐射耐受性的增加。我还将开发具有优化性能的全尺寸DMAP探测器，并追求这些设备进行粒子物理实验及其他设备的部署。这些新探测器在高光度LHC（HL-LHC）的计划升级和未来升级等实验中可能会产生巨大影响将使许多人可以使DMAPS跟踪检测器可用。
