In the context of the High Luminosity upgrade of the LHC, several components of the ATLAS detector will be renewed and improved to keep up with the increasing luminosity. In particular, High-Voltage Monolithic Pixel Sensors (HV-MAPS) are considered an alternative to conventional hybrid silicon pixels for the outer layers of the ATLAS Inner Tracker. HV-MAPS are based on HV-CMOS technology. It allows integrating an active pixel matrix that collects signal charges via drift and the full readout logic in a monolithic architecture.
The ATLASPix3 is the latest prototype of an ATLAS demonstrator chip. It is the first full-size version with an active area of 19.8 × 18.6 cm2 integrating pixels of size 150 × 50 µ m2. It also features time walk correction possibilities using ToA and ToT measurements.
In this talk, the latest results from the laboratory with a special focus on time resolution studies are discussed.
