A simple, compact, UHV compatible Mott polarization analyzer is described that employs electron accelerating voltages in the range 20ndash;40 keV.The analyzer provides excellent discrimination against inelastically scattered electrons and has the advantage that the major portion of the apparatus, and the scattered electron detectors, are operated near ground potential. The efficiency of the analyzer, sim;2times;10minus;5, is competitive with those provided by other polarimeters. The analyzer can measure the polarization of electron beams having currents as low as sim;10minus;13A and is suitable for use in a wide variety of experiments involving polarized electron beams.
