To achieve this goal and protect the machine from excessive radiation activation, an uncontrolled loss criteria of 1uA has been specified. Previous calculation for radiation shielding showed that high neutron and gamma were produced under this condition. To measure the high energy gamma ray(about 2 MeV ) at machine running and void damage by the prompt radiation, an air ionization chamber was designed to fulfill this goal. A Geant4 program was developed to simulate the energy response of detectors, the EM filed data was also taken into consideration in the programl. The simulation results indicate that the energy response linearity satisfies the requirement of the project specification.
