The P̄ANDA MVD silicon strip detector

Abstract

The PANDA experiment at the future FAIR facility will study annihilation reactions of antiprotons. The Micro-Vertex-Detector (MVD) as part of the tracking system will permit precise tracking and detection of secondary vertices. It is made of silicon pixel detectors and doublesided silicon strip detectors. The unique data acquisition concept without a central trigger poses a challenge to all sub-detectors. Developments for the MVD strip detector cover the evaluation of prototype sensors as well as the readout chain, ranging from the front-end for the trigger-less readout over the Module Data Concentrator ASIC to the off-detector electronics.

Triggerless readout architecture for the silicon pixel detector of the PANDA experiment

“…The ToPiX prototype, bump bonded with a prototype detector, has been tested in a beam test at the COSY facility at the FZ Juelich with a 2.7 GeV/c proton beam. Four pixel planes, with a sensitive area of 3.2 × 2 mm 2 , have been placed between a strip tracking station designed at the University of Bonn [10]. The strip station consists of four planes made with double side silicon strip sensors, with a pitch of 50 µm, a sensitive area of 1.92 × 1.92 cm 2 and a thickness of 300 µm.…”
