LHC ALICE实验中的内跟踪系统（ITS）正在升级改造中，该探测器采用厚度为50 μm的CMOS像素传感器（CPS）。IPHC正在开发两种CPS香料，MISTRAL和ASTRAL，旨在满足ITS升级的要求。第一个是来自为STAR-PXL探测器设计的MIMOSA 28传感器。第二种是在每个像素中集成一个CMOS，以提高读出速度和功耗。本文将详细描述传感器的开发并展示一些初步测试结果。
A detector, equipped with 50 μm thin CMOS Pixel Sensors (CPS), is being designed for the upgrade of the Inner Tracking System (ITS) of the ALICE experiment at LHC. Two CPS flavours, MISTRAL and ASTRAL, are being developed at IPHC aiming to meet the requirements of the ITS upgrade. The first is derived from the MIMOSA28 sensor designed for the STAR-PXL detector. The second integrates a discriminator in each pixel to improve the readout speed and power consumption. This paper will describe in details the sensor development and show some preliminary test results.
