Range of fast electrons in dielectrics

Velocity driving system for an in-field Mössbauer spectrometer

“…The resonance frequency f res decreases from 20 Hz for zero field to approximately 14 Hz for in-field measurements. Usually the velocity reference signal frequency is chosen close to the main mechanical frequency [2,19] to give the best regulation results. With this knowledge the velocity frequency f vel was set to 16 Hz for all spectra measurements.…”

Electron-beam charging of poly(methyl methacrylate)

“…It is noteworthy that the effect of space charge builtup during PMMA irradiation by fast electrons on their range was first revealed by Lackner et al [28] as the contraction of the glow area and was later confirmed by Evdokimov and Yagushkin [29]. However, such measurements basically indicate dose rate redistribution, rather than a change in the maximum electron range.…”
