Status of the 5 MeV Mott polarimeter design for the MESA — •Rakshya Thapa — Institut für Kernphysik, Mainz, Germany

A high intensity polarised beam has to be delivered to the P2 experiment at Mainz Energy Recovering Superconducting Accelerator Facility (MESA). The absolute error of the beam polarisation should be ≤1%. To track the polarisation, a Mott polarimeter will be installed after the pre-acceleration of the polarised beam to 5 MeV energy and measurements will be done in quasi-online mode with beam current ≈150 µA at ≤1% precision. For that, the polarimeter scattering chamber and its assembly in the beam line is being designed which will be reported.
