论文摘要
现在，整体上的主动像素传感器（地图）已被确定为跟踪带电颗粒的技术，尤其是在需要低材料预算的情况下。对于此类应用，传感器专注于空间分辨率和具有数字输出或适度电荷测量能力的像素非常适合。在欧盟强-2020项目中，重点是使用Hadron的实验，TIIMM（跟踪和离子识别材料预算最少）联合研究活动旨在将粒度图的能力扩展到用于离子物种鉴定的颗粒状图（ΔE）测量。 TIIMM原型是在塔爵士乐180 nm CMOS图像传感器（CIS）过程中开发的。阈值（TOT）方法应用于传感器以进行节能测量。这项工作介绍了最初TIIMM原型的实验室测量结果的主要设计细节和初步测试。
Monolithic active pixel sensors (MAPS) are now well established as a technology for tracking charged particles, especially when low material budget is desirable. For such applications, sensors focus on spatial resolution and pixels with digital output or modest charge measurement ability are well suited. Within the European Union STRONG-2020 project, which focuses on experiments using hadrons, the TIIMM (Tracking and Ions Identifications with Minimal Material budget) joint research activity intends to expand granular MAPS capacity to energy-loss (ΔE) measurement for ion species identification. The TIIMM prototypes are developed in the Tower Jazz 180 nm CMOS image sensor (CIS) process. The Time-Over-Threshold (ToT) method is applied to the sensor for the energy-loss measurement. The main design details and the preliminary test results from laboratory measurements of the initial TIIMM prototype are presented in this work.
