Comparison of charge distributions in FEP measured with thermal wave and pressure pulse techniques

Abstract

The spatial distribution of charges injected by monoenergetic electrons in Teflon FEP has been determined by two different techniques - the laser-induced pressure pulse (LIPP) technique and the laser-intensity modulation method (LIMM). A new numerical deconvolution technique for the LIMM is used. A comparison of the results provided by the two techniques shows good agreement.
