New methods for precision Møller polarimetry

Precision electron beam polarimetry is becoming increasingly important as parity violation experiments attempt to probe the frontiers of the standard model. In the few GeV regime, Møller polarimetry is well suited to high-precision measurements, however is generally limited to use at relatively low beam currents (< 10 μA). We present a novel technique that will enable precision Møller polarimetry at very large currents, up to 100μA
