Simple and compact low-energy Mott polarization analyzer

Abstract

A UHV compatible Mott polarization analyzer is described that employs electron accelerating voltages of ∼20 kV. The efficiency of the analyzer, ∼3×10−5, is competitive with those provided by other polarimeters. The present analyzer is considerably simpler and more compact than earlier designs and can be used to undertake energy- and angle-resolved polarization measurements with input beam currents below ∼10−14 A.
