Abstract
A simple electrostatic retarding potential analyzer configuration is described that gives a true measure of charged particle energy irrespective of the angle of incidence of the particles. The device has an inherently high energy resolution (.DELTA. E/E<0.01). The device eliminates errors in particle energy measurement usually associated with planar gridded RPA's. Electrostatic models and results from an experimental prototype indicate that the device can determine the energies of charged particles with a high degree of accuracy.
