MALTA: a Monolithic Active Pixel Sensor for tracking in ATLAS

The MALTA team is developing the MALTA chip, a depleted monolithic active pixel sensor (DMAPS) implemented in the TowerJazz 180 nm modified CMOS process for tracking applications in high energy particle physics experiments such as the ATLAS experiment at the LHC . At the INFIERI school in Wuhan, China, I presented results on what was then the latest prototype of the chip, the MiniMALTA. So far measurements have shown promising that suggest that the chip is operational after irradiation doses comparable to those predicted for the outer pixel layers of the proposed inner tracker (ITk) upgrade in ATLAS.
