The P2 Experiment at the new Mainz Energy-recovering Superconducting Accelerator (MESA) aims at measuring the weak mixing angle $\sin^2 \theta_\text{W}$ at low Q$^2$ with high precision. Therefore the polarization of the incident electron beam has to be known with a very high accuracy (< 0.5 %). A conventional Mott-polarimeter requires a lot of effort in calibration to be able to acieve this goal.

A Double Scattering Polarimeter (DSP) promises to meet these requirements with less effort.
