Abstract
A dual energy X-ray source for use in an explosive detection system includes only a single power supply and only a single X-ray tube. The X-ray tube includes only two electron guns and only a single anode. Each electron gun has its own grid and cathode. The X-ray source switches between producing a higher energy X-ray and producing a lower energy X-ray at a frequency of at least 4000 Hz.
