Abstract

The Proton Engineering Frontier Project has been constructing a 100-MeV Proton Linear accelerator for completion in 2013 and the accelerator design has been carried out with the objective of limiting beam losses to less than 1 W/m during normal operation. If accidental beam loss is to be prevented a beam loss monitor has to be installed along to the linear accelerator. Thus, to determine the dynamic ranges and the installation intervals of the beam loss monitors, we calculated the radiation field distribution by using the Monte Carlo Method not only during continuous beam loss for normal operation but also dose during accidental beam loss. The calculation results show that the intensity of neutron dose was higher than that of the gamma. The lateral distribution of neutrons was wider than that of photons.
