Abstract : The external proton beam of the Texas A. + M. University Variable Energy Cyclotron (TAMVEC) was studied to determine its suitability for special large-animal irradiations. Broad, uniform beams were produced by multiple-coulomb scattering of the narrow primary beam. Various energies were produced by placing absorbers in the beam or by varying the cyclotron energy, or by using both technics. Beam uniformity, energy, energy-spread, dose rate, and, in some instances, depth-dose profiles were measured in the exposure plane for a number of energies. The USAF School of Aerospace Medicine personnel measured depth-dose distributions with thermoluminescent dosimeters embedded in plastic phantoms. (Author)
