Measurements of Ion Kinetic Energy Distribution Using a Miniature Cylindrical Mirror Analyzer (CMA)—Application for H⁺ Desorption Induced by Core-Level Excitations of Condensed Water

Abstract

We have developed a miniature cylindrical mirror analyzer (CMA) for ion kinetic energy measurements. The CMA consists of a shield for electric field, inner and outer cylinders, a pinhole, and microchannel plates. We have applied it for the measurements of kinetic energy distribution of H⁺ desorbed by O 1s transitions of condensed H₂O.
