CMOS Monolithic Active Pixel Sensors — •Michael Deveaux — GSI Darmstadt

Being pioneered by the IPHC Strasbourg, CMOS Monolithic Active Pixel Sensors for charged particle tracking feature an attractive combination of highest detection efficiency, spatial precision (∼ 5  µ m) and low power dissipation. The 50  µ m thin sensors may be combined with ultra-light support structures and cooling systems. Thanks to progress in CMOS industry and the joined efforts of the community, their rate capability and radiation tolerance were improved by several orders of magnitude during the past 20 years. The maturity reached nowadays allows to use the sensors in multiple applications requiring highest tracking precision in combination with advanced rate capability and time resolution. This includes state-of-the-art tracking and vertex detectors as known from STAR, ALICE, the future CBM experiment and possibly future charm and Higgs factories.

The contribution summarizes the features, capabilities and remaining limitations of the technology and gives a brief insight into current R&D activities within and beyond the hadron physics community.
