APPLICATIONS OF THE PHOTONUCLEAR FRAGMENTATION MODEL TO RADIATION PROTECTION PROBLEMS
In order to provide radiation protection systems for high energy electron accelerators it is necessary to define the yields of hadrons produced when the electron beam interacts with a fixed target. In practical terms this will occur when any beam or fraction of the beam is lost from the accelerator orbit or when any fraction of the beam is intercepted by a target inserted in the path of the beam or when the beam is totally absorbed by a beam dump. The electron and gamma yields from these interactions are well characterized and amenable to calculation utilizing Monte Carlo shower codes. However, the yield of hadrons has been less well defined. Neutron production has received most attention because of its importance to radiation shielding. Production mechanisms such as the giant dipole and the quasi-deuteron resonances have provided valuable information for total neutron yields for electron beams at energies less than about 400 MeV. For electron beams at energies extending to 10 GeV it is necessary to include the higher energy resonance structures and the various intranuclear production channels that are available for the production of higher energy neutrons. The production model described in this paper permits the calculation of laboratory angle and energy of all hadrons produced when an electron beam of energy between 100 MeV and 10 GeV interacts with a fixed target. This model can be used as an event generator for Monte Carlo codes used for many radiation protection purposes including calculation of radiation shielding.
