Achievements of CMOS Pixel Sensors for the CBM Micro-Vertex Detector 1

CMOS pixel sensors are being developed for the CBM Micro-Vertex Detector (MVD). They provide the high resolution required to reconstruct efficiently decay vertices of short-lived particles, such as charmed mesons. The present R&D is mainly driven by the severe running conditions expected in the vicinity of the experimental target. The most significant outcome obtained in 2007 is summarised hereafter. Prominent results include performances of a fast sen sor architecture with discriminated outputs, the toleranc e to non-ionising radiation, the design of a zero-suppressio n micro-circuit and industrial thinning. The report also giv es an overview of the R&D plans for 2008.
