UHV-compatible Mott polarimeters that employ electron accelerating voltages of $\sim$20kV have been designed and tested. The efficiency of the polarimeters, $\sim$3 $\times$ 10$\sp{-5}$, is competitive with those provided by other polarimeters, but the present polarimeters are considerably simpler and more compact. The scattering efficiency of the polarimeters is 2.2 $\times$ 10$\sp{-3}$, which makes it possible to accurately measure electron spin polarizations using input beam currents as low as 10$\sp{-14}$A. One polarimeter design incorporates an in-line retarding potential energy analyzer with an energy resolution $\sim$0.5eV, and is suitable for a wide variety of applications requiring energy- and angle-resolved polarization measurements.
