Abstract
The work focuses on the study of vacuum Compton detector( VCD) with flat energy response. The proposed VCD adopts a compensation design of the emitter, i. e. a superimposition of materials of varied thicknesses, and is optimized with Monte Carlo method. The optimally designed VCD consists of an emitter with the superimposition of 0. 01, 1 mm-thick Au, a 3 mm-thick Fe front window and a 3 mm-thick Pb shielding. Its non-flatness of energy response to gamma-ray is less than 10. 7% over 0. 4-7. 0 MeV energy zone. The flatness of energy response to gamma ray of this VCD is more excellent than current gamma detectors'.关键词
