Carbon-12 target for P2 — •Kathrin Gerz — Institut für Kernphysik Mainz
The P2-Experiment at the Mesa accelerator - due to be operational in 2017 - in Mainz aims to determine the electro-weak mixing angle with a relative precision of 0.15% by measuring the parity-violating asymmetry in elastic scattering of electrons from nuclei at low Q2.
The current approach is based on a 60cm long liquid hydrogen target. Studies are under way to investigate alternative target materials. This poster will show first results of simulations for an experimental setup with a graphite target as well as potential advantages and experimental challenges as compared to cryogenic hydrogen.
