Abstract

A beam loss monitoring system is being designed for PEFP(Proton Engineering Frontier Project) by Korea Atomic Energy Research Institute(KAERI). The beam loss monitoring system is based on the ion chamber and an electrometer. An air-filled ion chamber was designed and fabricated as a prototype detector of beam loss monitor. The radiation response of the ion chamber was simulated by using EGSnrc code. The collection efficiency and stability of the ion chamber with respect to the different radii of inner electrodes is discussed. The proper choice of high voltage bias polarity for the ion chamber is also studied. The test of the ion chamber under high dose rate is under way at KAERI gamma irradiation facility at the exposure rate of 106R/h.
