Determination of Total X-Ray Beam Energy With a Calibrated Ionization Chamber

From Abstract: "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. This report can be used to construct a replica chamber to determine its absolute calibration between 6 and 170 Mev under a variety of experimental conditions."
