Towards the Pre-Production Module of the Largest Station of the CBM MVD — •Franz Alexej Matejcek for the CBM-MVD collaboration — Goethe-Universität Frankfurt
The Micro Vertex Detector (MVD) of the Compressed Baryonic Matter Experiment (CBM) consists of four planar stations, each built of four independent quadrants (modules), that are equipped with dedicated CMOS pixel sensors (MIMOSIS) and will operate in vacuum. Each detector plane features a material budget x/X0 ranging between 0.3 and 0.5 %, depending on size. The sensors are glued onto 380 µm thick TPG (Thermal Pyrolytic Graphite) carriers that provide the necessary mechanical stiffness and a high thermal conductivity in the geometrical acceptance to cool the sensors well below 0 ∘C. The sensor are then wire-bonded to dedicated flex cables connecting the front end electronics which are mounted on a heat sink sitting outside the acceptance. The integration is mechanically challenging as the sensors have to be glued and bonded on both sides of the carrier to maximize the acceptance.
This contribution will focus on integration aspects of the pre-production module of the largest quadrants.
