论文摘要
当前和将来的加速器设施中的定时信息对于在检测系统上极大的颗粒多重性中解决对象（粒子轨道，淋浴等）很重要。 picosec微瘤检测器已证明具有Sub-25 \，PS精度为150 \，GEV MUON的能力。在详细的仿真研究和一个现象学模型的驱动下，从随机描述了信号形成的动力学，开发了新的Picosec设计，可显着改善检测器的时序性能。 Picosec原型的漂移间隙尺寸降低（$ \ sim $ \ si {119} {\ micro \ meter}）在激光束测试中的定时单光子中达到了45 \的分辨率（相比之下，与标准PICOSECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECECTECTER中的单个光子中的PS达到了。在大面积探测器上，已经开发和研究了带有分段阳极的多pad Picosec原型。粒子梁中的广泛测试表明，即使在几个相邻的垫子之间共享诱导的信号时，多pad PicoSec技术也提供了非常精确的时机。此外，已经开发了新的信号处理算法，可以在数据获取过程中应用，并提供实时，精确的时机。
Timing information in current and future accelerator facilities is important for resolving objects (particle tracks, showers, etc.) in extreme large particles multiplicities on the detection systems. The PICOSEC Micromegas detector has demonstrated the ability to time 150\,GeV muons with a sub-25\,ps precision. Driven by detailed simulation studies and a phenomenological model which describes stochastically the dynamics of the signal formation, new PICOSEC designs were developed that significantly improve the timing performance of the detector. PICOSEC prototypes with reduced drift gap size ($\sim$\SI{119}{\micro\metre}) achieved a resolution of 45\,ps in timing single photons in laser beam tests (in comparison to 76\,ps of the standard PICOSEC detector). Towards large area detectors, multi-pad PICOSEC prototypes with segmented anodes has been developed and studied. Extensive tests in particle beams revealed that the multi-pad PICOSEC technology provides also very precise timing, even when the induced signal is shared among several neighbouring pads. Furthermore, new signal processing algorithms have been developed, which can be applied during data acquisition and provide real time, precise timing.
