A Monte Carlo Simulation Study of a Flat-Panel X-Ray Source
Applied Radiation and Isotopes
Abstract
A novel flat-panel transmission X-ray source based on nitrogen-incorporated ultra-nano-crystalline diamond (N-UNCD) field emitters is being developed for medical and industrial X-ray imaging. X-ray generation characteristics of the X-ray tubes were simulated with the MCNPX 2.6.0 Monte Carlo code. The simulation results showed that 0.25-12µm thick tungsten targets could generate an adequate intensity of Bremsstrahlung X-rays. Generated X-ray output intensities of 1.48×10 12MeV/mA-s of 100kVp electrons hitting the target were found before collimation.
