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.
The photon energy flux density for the measured spectrum was converted to an equivalent roentgen rate value, which agreed within 10 percent with the value obtained from measurements made with a Victoreen thimble chamber.
