Title: 5 MeV Mott Polarimetry at MESA

Speaker: Rakshya Thapa

Abstract: Parity-violating experiments like P2 at Mainz Energy-Recovering Superconducting Accelerator (MESA) demand accuracy of polarization measurement of ¿P/P < 1 %. To ensure electron beam polarization, a polarimetry chain with polarimeters at different energies is planned. This will help to track the beam polarization throughout the MESA lattice. A 5 MeV Mott polarimeter is planned as a part of the chain. This polarimeter is planned to run parallel to the Moller polarimeter and P2 experiment to cross-validate the polarimeters and ensure the beam polarization at the experiment. The parallel run is possible with the fast kicker, which can kick the beam at different duty factors. In this talk, design of the Mott polarimeter will be reported along with the preliminary plan of the detector system.
