HK 40.3: Vortrag
Mittwoch, 1. April 2020, 17:30–17:45, J-HS K
The front-end signal path of the P2 experiment at MESA — Sebastian Baunack1, Michael Gericke3, Kathrin Imai1, •Rahima Krini1, Werner Lauth1, Frank Maas1,2, David Rodriguez Pineiro2, and Malte Wilfert1 — 1Institute for Nuclear Physics, Mainz, Germany — 2Helmholtz Institute Mainz, Germany — 3University of Manitoba, Canada
The MESA accelerator will be built in the Institute for Nuclear Physics in Mainz. In this facility the parity-violating asymmetry of the elastic electron-proton scattering will be measured with high precision at the P2 experiment, in order to determine the weak mixing angle sineff2(θ). Therefore, many technical challenges have to be solved.
The small asymmetries O(10−8) and the high precision require very high statistics and therefore a long measurement time. A joint read-out electronics for P2 experiment in Mainz and for Moeller experiment at the Jefferson Laboratory is under development by collaborators of University of Manitoba. The challenge is to control the integrating detector signal chain and all sources of electronics noise within the whole experimental P2 set-up. A first prototype was build and tested at MAMI (Mainzer Mikrotron).
