Abstract

Abstract

It was hard to measure the fluence of pulse hard X-ray directly in the field of high power particle beam. The method of measuring the fluence of pulse hard X-ray was defined, and the basic theory of full-cell processes was introduced. The phototubes and LSO scintillators were used to develop the measurement system. The influence of all measurement units was analysed. By using the MCNP Monte-Carlo code, the energy deposition and transmissivity in axial region of the LSO scintillators were calculated when the photons of different energies irradiated the scintillators of different thicknesses. The thickness of the LSO scintillator was given, which was 20 mm. The collimation system and anti-electromagnetic interference system were designed. The signal-to-noise ratio was added.
