Abstract :
A novel proposal of using polarized atomic hydrogen gas, stored in an ultracold magnetic trap, as the target for electron-beam polarimetry based on Moller scattering is discussed. Such a target of practically 100% polarized electrons could provide a superb systematic accuracy of about 0.5% for beam polarization measurements. Feasibility studies for the CEBAF electron beam have been performed.
