耗尽单片有源像素传感器（DMAPS）原型开发的TowerJazz 180 nm CMOS成像过程中已被设计的ATLAS升级第二阶段在HL-LHC的背景下。像素传感器的特点是收集电极小（3 μm），以最大限度地减少电容，像素尺寸小（36.4× 36.4 μm2），并在高电阻率外延p型硅上生产。该设计的目标辐射硬度为1×1015 1 MeV neq/cm 2，与ATLAS ITK Pixel探测器的最外层兼容。本文介绍了从粒子束测试的Mini-MALTA原型，实现了掩模的变化或额外的植入，以解决像素边缘的效率低下的表征结果。结果表明，在1×1015 1 MeV neq/cm 2的剂量后，完全效率。
Depleted Monolithic Active Pixel Sensor (DMAPS) prototypes developed in the TowerJazz 180 nm CMOS imaging process have been designed in the context of the ATLAS upgrade Phase-II at the HL-LHC. The pixel sensors are characterized by a small collection electrode (3 μm) to minimize capacitance, a small pixel size (36.4× 36.4 μm2), and are produced on high resistivity epitaxial p-type silicon. The design targets a radiation hardness of 1×1015 1 MeV neq/cm2, compatible with the outermost layer of the ATLAS ITK Pixel detector. This paper presents the results from characterization in particle beam tests of the Mini-MALTA prototype that implements a mask change or an additional implant to address the inefficiencies on the pixel edges. Results show full efficiency after a dose of 1×1015 1 MeV neq/cm2.
