Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

The characteristic X-ray of a target is of considerable significance in industrial applications and medical diagnosis and treatment, and its intensity is closely related to the incident electron energy. At a high energy, it is not easy to determine the relation between characteristic X-rays and the incident electron energy through measurements, but the Monte Carlo method has a wide energy calculation range. In this study, the X-ray energy spectra of six target materials (Cu, Mo, Rh, Ag, W, and Pt) were simulated at various incident electron energies (<3 MeV) using the Monte Carlo code MCNP5 and the relation curve between the characteristic X-ray intensity of each of the target materials, and the incident electron energy was obtained through a simulation. A Si-PIN detector was used to measure the low-energy output energy spectra of two X-ray tubes (Ag and W targets). The relation curve between the X-ray tube excitation voltage and the characteristic X-ray intensity was obtained by fitting the measured data to a linear function. The simulation fitting curve and measurement fitting curve agreed well in the low-energy range. Comparisons of the calculated and measured values revealed that most of the deviations for the Ag target were less than 5%, and those for the W target were less than 6%.
