"Polarized Electron Source for the MOLLER Experiment"

The MOLLER experiment at Jefferson Laboratory will be part of a new generation of ultra high precision electroweak experiments. It will measure the Moller (electron-electron scattering) parity-violating asymmetry, providing an unprecedented precision on the electroweak mixing angle. To achieve such small uncertainties, innovative techniques in the electron source are required to switch the beam helicity more quickly than previously achievable. A key technology is the Pockels cell in the laser optics of the polarized electron source. RTP crystals have been demonstrated to achieve almost an order of magnitude faster transition times than commonly used KD*P crystal cells and are promising for the future Moller Experiment.
