Description
The MVTX tracking detector in the sPHENIX experiment at the RHIC accelerator complex at BNL, is a Monolithic Active Pixel Sensor (MAPS) silicon detector that is based on the three inner most layers of the ALICE ITS2 tracking system. The design and installation of this detector into the sPHENIX experiment will be described in detail. The overall length and diameter of this detector assembly is 1,835.0 mm long, the diameter of the sensor region is 106.0 mm and the diameter of the service barrel is 215.0 mm. The entire detector is designed to be cantilevered off the end flange of the service barrel. The detectors mass is 24.0 kg. The integration of this detector was a key engineering issue with both the beampipe and outer tracking detectors already installed leaving minimal radial gaps to work with.
