论文摘要
LF-Monopix1和TJ-Monopix1分别是150 nm Lfoundry和180 nm TowerJazz CMOS技术的耗尽的单片活性像素传感器（DMAPS）。它们设计用于在高速度和高辐射环境中使用，例如高亮度大型强调对撞机（HL-LHC）的Atlas Inner Tracker。这两个芯片均使用列排列读取体系结构读取。 LF-Monopix1遵循具有大电荷收集电极的设计，其中读出电子设备放置在内部。通常，这在传感器和短漂移距离中提供了均匀的电场。 TJ-Monopix1采用与电极分离的读出电子设备和额外的N型植入物的小电荷收集电极，以实现敏感体积的全部耗竭。这种方法具有低传感器电容，因此具有低噪声，通常用小像素大小实现。使用实验室测试和颗粒梁在辐照之前和之后都表征了两个检测器。
LF-Monopix1 and TJ-Monopix1 are depleted monolithic active pixel sensors (DMAPS) in 150 nm LFoundry and 180 nm TowerJazz CMOS technologies respectively. They are designed for usage in high-rate and high-radiation environments such as the ATLAS Inner Tracker at the High-Luminosity Large Hadron Collider (HL-LHC). Both chips are read out using a column-drain readout architecture. LF-Monopix1 follows a design with large charge collection electrode where readout electronics are placed inside. Generally, this offers a homogeneous electrical field in the sensor and short drift distances. TJ-Monopix1 employs a small charge collection electrode with readout electronics separated from the electrode and an additional n-type implant to achieve full depletion of the sensitive volume. This approach offers a low sensor capacitance and therefore low noise and is typically implemented with small pixel size. Both detectors have been characterized before and after irradiation using lab tests and particle beams.
