论文摘要

高压单层活性像素传感器（HV-MAP）基于商业高压CMOS工艺，并通过在反向偏置二极管内漂移来收集电荷。 HV-MAP代表了未来像素跟踪探测器的有前途的技术。提出了两项最新发展。 Mupix具有连续的读数，正在为MU3E实验开发，而Atlaspix则是针对具有触发读数的LHC应用程序开发的。这两个变体都有一个完全整体的设计，包括州机器，时钟电路和串行驱动程序。在实验室和测试板运动中表征了几种原型和设计变体，以测量效率，噪声，时间分辨率和辐射耐受性。提出了最近的Mupix和Atlaspix原型的结果，并讨论了未来改进的前景。

High Voltage Monolithic Active Pixel Sensors (HV-MAPS) are based on a commercial High Voltage CMOS process and collect charge by drift inside a reversely biased diode. HV-MAPS represent a promising technology for future pixel tracking detectors. Two recent developments are presented. The MuPix has a continuous readout and is being developed for the Mu3e experiment whereas the ATLASPix is being developed for LHC applications with a triggered readout. Both variants have a fully monolithic design including state machines, clock circuitries and serial drivers. Several prototypes and design variants were characterised in the lab and in testbeam campaigns to measure efficiencies, noise, time resolution and radiation tolerance. Results from recent MuPix and ATLASPix prototypes are presented and prospects for future improvements are discussed.
