A modified Rice University-type compact Mott spin polarimeter operating at 20 kV is adapted to a large commerical hemispherical electron energy analyzer. Normal energy analyzer functions are preserved via a retractable channeltron in the polarimeter acceleration column. In the spin-detection mode, the polarimeter permits analysis of two orthogonal transverse spin-polarization components. Electron trajectory analysis is used to optimize polarimeter lens column voltages in both normal and spin-detection modes. Performance levels are established by experiments and significantly improved spin-detection efficiency is shown to be accessible by changes in the polarimeter collection solid angle.
