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.

Abstract: A cathode system for an x-ray tube has an electron emitter and a further electrode arranged between electron emitter and the x-ray tube anode. This further electrode can be connected to a potential deviating from the potential of the electron emitter with a switching stage having a pulse-pause (on-off) ratio set to produce the desired tube current.

Abstract: An X-ray stereoscopic cinematography apparatus including an X-ray tube having at least a pair of focal spots from which X-rays are irradiated independently at an object to produce an X-ray image of an object under study, means for converting the X-ray image to an optical image, an optical system device for distributing the optical image to first and second cinecameras. The optical system device includes a first half-mirror having a reflection rate of approximately fifty percent and a second half-mirror having a comparatively low transmission rate, the half-mirrors being separately positionable in a first position to reflect the optical image or a second position out of the light path of the optical image to distribute the optical image to the first and second cinecameras. A television camera is provided to accept the optical image delivered through the optical system device and to convert it to an electric signal. A mode setter enables the selection of one of a stereoscopic cinematography mode, a single cinematography mode, and a fluoroscopy mode.
