Eleven-Mev Thick Target Bremsstrahlung

Abstract
The intensity distribution of the photons in the forward direction from the 60-mil tungsten wire target of the U. S. Naval Ordnance Laboratory 11-Mev betatron was determined in an energy range of 0.3 to 12 Mev from measurements made with a magnetic Compton spectrometer. The experimental results showed good agreement with the Bethe-Heitler bremsstrahlung theory after corrections were made for target thickness effects and the absorption produced by materials in the path of the photon beam.
