论文摘要
未来几年，大型强子对撞机的计划的发光度增加引发了人们对使用粒子到达时间作为专用检测器中的其他信息的兴趣，以减轻堆积的影响。所需的时间分辨率是数十秒的顺序，其空间粒度为1 mm。在此精度水平上的时间测量也将引起LHC之外的高能粒子物理学。我们在本文中介绍了具有高分辨率的时间测量能力的辐射硬耗尽的单片活性像素传感器（DMAP）的最初发展。所选的技术是标准的高压CMOS工艺，结合高电阻率检测器材料，该材料已被证明可以在数百MRAD辐射后有效地检测到跟踪应用中的颗粒。
The planned luminosity increase at the Large Hadron Collider in the coming years has triggered interest in the use of the particles' time of arrival as additional information in specialized detectors to mitigate the impact of pile-up. The required time resolution is of the order of tens of picoseconds, with a spatial granularity of the order of 1 mm. A time measurement at this precision level will also be of interest beyond the LHC and beyond high energy particle physics. We present in this paper the first developments towards a radiation hard Depleted Monolithic Active Pixel Sensor (DMAPS), with high-resolution time measurement capability. The technology chosen is a standard high voltage CMOS process, in conjunction with a high resistivity detector material, which has already proven to efficiently detect particles in tracking applications after several hundred of Mrad of irradiation.
