Many years of research and development of High Voltage Monolithic Active Pixel Sensors (HVMAPS) have culminated in the final design for the Mu3e pixel sensor, MuPix11. Following the requirements of the Mu3e experiment MuPix11 has been developed to provide excellent vertex, time and momentum resolution in a high rate environment and allowing to construct ultra-thin detector layers with...

AstroPix is a novel high-voltage CMOS active pixel sensor being developed for a next generation gamma-ray space telescope, AMEGO-X, and the ePIC electron-iron collider detector. AstroPix has to be $500~\rm{\mu m}$ thick and to be fully depleted by supplying bias voltage. The energy resolution must be < 6 keV (FWHM) at 60 keV and the pixel pitch should be $500\times500~\rm{{\mu m}}^2$....

The RD50-MPW4, the latest HV-CMOS pixel sensor in the series from the CERN-RD50-CMOS group, advances radiation tolerance, granularity, and timing resolution for future experiments like HL-LHC and FCC. Fabricated by LFoundry in December 2023 using a 150nm CMOS process, it features a 64 x 64 pixel matrix with a $62 \times 62\mu m^2$ pitch and employs a column-drain readout architecture. The...

Talk

Monolithic active pixel sensors with depleted substrates present a promising option for pixel detectors in high-radiation environments. High-resistivity silicon substrates and high bias voltage capabilities in commercial CMOS technologies facilitate depletion of the charge sensitive volume. TJ-Monopix2 and LF-Monopix2 are the most recent large-scale chips in their respective development line,...
