Beam Parameter Requrements for Radiography

Abstract: With the Monte Carlo method, the performance of X-ray source of a flash X-ray radiographic machine is simulated. It is not true that the smaller the beam radius and the emittance, the better the performance of radiographic image. The results indicate that there is a joint restriction on the beam radius and the beam emittance. If the beam radius on the target is 0.12cm and the exposure inhomogeneity within the azimuthal angle of 2°is not lager than five percentage, the normalized emittance of the beam should not be less than 550cm.mrad.
