在过去的几年里，LHC对撞机上的LHCb探测器已经非常成功地运行，为标准模型提供了新的和深刻的见解，特别是通过研究b-强子来更好地理解CP破坏。LHCb的关键组件之一是其粒子识别系统，由两个RICH探测器组成，可以在大动量范围内高精度分离粒子种类。为了在LHCb升级的基础上保持和提高粒子识别系统的性能，已经提出了TORCH探测器来补充低动量（2-10 GeV/c）的RICH系统。TORCH探测器通过精确计时通过它的粒子来提供（带电）粒子识别。假设从跟踪中获得的动量已知，则可以从粒子从其主顶点的飞行时间推导出粒子的种类。这种测量是通过对固体辐射器中产生的光子进行计时和组合来实现的。探测器的几何形状（由大块熔融石英板组成）使得产生的切伦科夫光子通过全内反射被捕获在板内，并传播到辐射器的外围。在这里，它们被投射到光电探测器的平面上，光电探测器由专门设计的MCP-PMT组成。针对轨道检测到的光子被组合成每个粒子的时间戳，最终导致测量飞行时间，从而可以导出粒子身份。TORCH项目的最终目标是证明TORCH探测器作为LHCb粒子识别系统的补充的可行性和可取性。本论文将描述TORCH项目关键目标所取得的进展;特别是光学、探测器和电子学的发展。人们喜欢好奇，这是科学的种子
The LHCb detector at the LHC collider has been very successfully operated over the past years, providing new and profound insights into the Standard Model, in particular through study of b-hadrons to achieve a better understanding of CP violation. One of the key components of LHCb is its particle identification system, comprised of two RICH detectors, which allow for high precision separation of particle species over a large momentum range. In order to retain and improve the performance of the particle identification system in light of the LHCb upgrade, the TORCH detector has been proposed to supplement the RICH system at low momentum (2-10 GeV/c). The TORCH detector provides (charged) particle identification through precision timing of particles passing through it. Assuming a known momentum from the tracking, it is possible to derive the species of a particle from the time of flight from its primary vertex. This measurement is achieved by timing and combining photons generated in a solid radiator. The geometry of the detector (composed of large plates of fused silica) is such that the generated Cherenkov photons are trapped inside the plate by total internal reflection, and propagate to the periphery of the radiator. Here they are projected onto a plane of photodetectors, comprised of purpose designed MCP-PMTs. The photons detected for a track are combined into a time stamp for each particle, finally resulting in the time of flight being measured so that the particle identity can be derived. The final goal of the TORCH project is to prove the feasibility and desirability of the TORCH detector as an addition to the LHCb particle identification system. This thesis will describe the progress that has been made towards the key objectives of the TORCH project; in particular the development of optics, detectors and electronics. Men love to wonder and that is the seed of science
