16.3: Ion‐Induced Secondary Electron Emission: A Comparative Study

Abstract

Abstract Ion‐induced secondary electron emission coefficients for Ne, Ar, and Xe discharges are reproducibly determined using V‐Q Lissajous figures. The comparison of measured and calculated Paschen curves results in ion‐induced γ‐coefficients for glass, MgO, CVD diamond, and phosphors. The measured γ‐values correlate well with a simple model based on the ionization energy of the gas ion and the band gap and electron affinity of the solid.
