Development of detector read-out electronics for the P2 experiment at MESA — •Rahima Krini1, Sebastian Baunack1, Dominik Becker1, Michael Gericke2, Frank Maas1,3,4, and David Rodriguez Pineiro3 for the P2 collaboration — 1Institute for Nuclear Physics, Mainz, Germany — 2University of Manitoba, Canada — 3Helmholtz Institute Mainz, Germany — 4PRISMA Cluster of Excellence, Mainz
The Mainz Energy recovering Superconducting Accelerator (MESA) is being built at the Institute for Nuclear Physics in Mainz. At MESA the P2 experiment is planned for a precision measurement of the weak mixing angle. It presents the most challenging parity-violation experiment with a relative uncertainty of Δ APV/APV ≈ 2.41 %.
The small asymmetries O(10−9) and the high precision require very high statistics and therefore a long measurement time. The Cherenkov ring detector consists of fused silica bars equipped with photomultiplier tubes with high quantum efficiency. The challenge is to control the integrating detector signal chain and all sources of electronics noise within the whole experimental P2 set-up. The first preliminary results of the main front-end components will be presented.
