摘要:

高亮度大型强子对撞机的升级将对所有实验的跟踪系统提出前所未有的挑战。在CMOS工艺中设计的有源像素检测器的最新进展为使用无源传感器的成熟混合设计提供了有吸引力的替代方案。本文介绍了一个高压CMOS有源像素传感器的ATLAS跟踪器升级设计的研究。传感器被粘在可插入B层的读出芯片上。被测器件的像素比所附读出芯片的像素更小,输出信号中编码有关于命中CMOS像素的信息(子像素编码)。描述了将读出芯片中记录的命中映射到CMOS像素的测试光束测量,从而验证子像素编码。

英文摘要:

The upgrade to the High Luminosity Large Hadron Collider will pose unprecedented challenges to the tracking systems of all experiments. Recent advancement of active pixel detectors designed in CMOS processes provide attractive alternatives to the well-established hybrid design using passive sensors. This article presents studies with a high-voltage CMOS active pixel sensor designed for the ATLAS tracker upgrade. The sensor is glued to the read-out chip of the Insertable B-Layer. The device under test is structured in smaller pixels than those of the attached read-out chip with information on the hit CMOS pixel encoded in the output signal (subpixel encoding). Test beam measurements mapping recorded hits in the read-out chip to CMOS pixels, thus validating the subpixel encoding, are described.
