Determination of total x-ray beam energy with a calibrated ionization chamber. Final report
Technical Report
·
OSTI ID:7251346
This report describes the use of an air-filled aluminum-alloy ionization chamber to determine the energy transported by a bremsstrahlung beam with maximum photon energy in the range 6 to 170 MeV. The experimental calibrations of this chamber over this energy range are given, as well as the results of calibration experiments made with a 250-kV constant-potential X-ray tube and with /sup 137/Cs and /sup 60/Co gamma-rays. Information is presented about the change in calibration when the chamber is used with different experimental conditions, and when either its dimensions or its alloy composition are changed slightly. This report can be used to construct a replica chamber and to determine its absolute calibration between 6 and 170 MeV under a variety of experimental conditions. (GRA)
