Thin-Foil Calorimeters for the Measurement of Energy Deposition Profiles and Spatial Fluence Distributions of Low-Energy Pulsed Electron Beams,
Abstract
A thin-foil calorimeter designed to measure energy deposition profiles for electrons with ranges less than 100 micrometers has been tested with two pulsed electron beams. In addition to the diagnostic determination of the beam spectra obtained from the measured deposition profiles, the spatial fluence patterns of the beams have been measured with a total-stopping calorimeter array. The calorimeters are capable of operation over a dose range of a few kilorads to nearly 100 Mrad. Fluence measurements with the calorimeters can be made accurately with the error probably not exceeding 2 percent. In contrast, the dose-path measurements are less accurate although the probable error has not been determined. (Author)
