Abstract :
Measurement techniques of volume charge distribution within insulating materials are developed using a pulsed electroacoustic method. The fundamental equation of the relation between the charge distribution in the insulating material and the signal voltage from the electroacoustic transducer is presented along with the typical measured charge profiles in polymethylmethacrylate (PMMA) during and after electron-beam irradiation
