Studies on Alternative Sensor Carrier Concepts for the CBM MVD* — •Fabian Hebermehl for the CBM-MVD collaboration — Goethe-Universität Frankfurt
The Micro Vertex Detector (MVD), part of the Compressed Baryonic Matter (CBM) Experiment at the future FAIR facility, comprises four detector stations, of four 0.3−0.5 % X0 thin quadrants, respectively. As the MVD will be operating in vacuum, efficient thermal management by the carrier of the sensors is mandatory. For this reason, the carrier materials chosen are Thermal Pyrolitic Graphite (TPG) for the larger stations and pCVD diamond for the smallest, first station. Studies have been conducted on alternative concepts for the TPG stations to balance thermal performance, material budget and production yield. The station production yield is driven by the need to populate both carrier sides with large-area MIMOSIS sensors to minimize inactive areas inside the detector acceptance. The options to (i) integrate ladders rather then carrier plates and (ii) separate front and back side sensor integration have been studied. The contribution will summarize the findings and gives a recommendation of which design is best suited for refining MVD station concept accordingly.
