The Belle II experiment currently records data at the SuperKEKB e+e- collider, which holds the world luminosity record of
Coarsely segmented Si diode detectors are widely used in space applications for measuring the mixed radiation fields. Starting in 2012, when 5 Timepix chips were installed at the International Space Station hybrid pixel detectors have entered space radiation dosimetry and monitoring. The problems to be solved for measuring GCR and SEP events are the dynamic range of the charge signal which...
A MAPS based inner tracker is proposed for the Super Tau-Charm Facility, a next-generation high-luminosity electron-positron collider operating in the tau-charm energy regime. In order to satisfy the challenge of high luminosity, high event rate, and the high tracking performance of benchmark physics programs, the inner tracker has to be of low power consumption, low material budget and...
PSI is developing DMAPS prototype chips with time of arrival measurements for potential use in small scale physics experiments at PSI and also for detectors used outside the field of particle physics.

Several process modifications, and front-end improvements have been implented on several prototypes that have resulted in...
The High-Voltage CMOS technology is intrinsically radiation-hard and fast at charge collection, making it a promising technological option for tracking detectors at future experiments requiring large-area coverage, high spatial resolution and radiation tolerance.

This is not a project proposal, but was meant as a WP1 discussion contribution: Experience has shown that the availability of proprietary processes that we invested a lot of money and manpower into is not guaranteed. One possible mitigation might be to evaluate "OpenSource" processes (ideally including OpenPDKs, OpenSource documentation of the process details like doping profiles and...
