Abstract: This invention relates to a flexible ionizer. In an ionizer that uses soft X-ray and comprises a head unit generating soft X-ray whose wavelength is 1.2 ~ 1.5 A, a soft X-ray protect unit shielding the leak of the soft X-ray from said head unit, and a power control unit supplying control signal and control voltage to the head unit, the head unit the flexible ionizer of this invention is positioned outside of the soft X-ray protect unit and the flexible ionizer further comprises a flexible tube protecting a high voltage cable that connects said head unit and said power control unit from external impact or vibration and letting the user bend the head of said head unit at an arbitrary angle toward a charged body if necessary, a first connecting means letting the ions generated at the window positioned inside of the body of the ionizer emit toward the charged body by connecting one end of said flexible tube and said head unit, and a second connecting means connecting the other end of said flexible tube and the body of the ionizer. In this case this invention is characterized in that it molds the high voltage power lines in the flexible tube in order to prevent from short circuit's occuring at a near distance between the high voltage power lines and to prevent from mutual induction voltage's occuring, wherein the short circuit and the mutual induction voltage are caused by the mutual influence of the high voltage lines.

Abstract: The envelope comprises a window made of material transparent to the radiation emitted by the source that comprises at least one chamber (20, 22, 23) in which can be moved a material impervious to the electromagnetic radiation, the chamber being shaped such that the material impervious to the radiation can be inserted from outside the chamber and that inside the chamber the material impervious to the radiation surrounds a radiation beam passage zone, such that the surface of the beam passage zone vaires according to the volume of the impervious material in the chamber, thus eliminating the extrafocal stray radiation. The invention is useful in X-ray imaging apparatus.

Abstract: An X-ray tube arrangement (120) for dual energy operation is proposed. The arrangement comprises an electron source (210) for emitting an electron beam (215) and a disk-shaped anode (230). Furthermore, a rotatable filter arrangement (125) is provided comprising a toroidal filter (126) with a filter pattern comprising an X-ray absorption portion arranged along a circumference of the toroidal filter (126). The rotatable filter arrangement (125) is adapted to rotate the toroidal filter around a rotation axis (237) orthogonal to the disk-shaped anode (230). The filter arrangement (125) may be attached to the tube housing (122) such that the toroidal filter (126) is held by a bearing (124). Alternatively, the toroidal filter (126) may be attached to the anode (230). Gyroscopic forces resulting upon filter (126) rotation may be reduced especially when applied in a rotating gantry of a CT device.

Abstract: A dual energy X-ray source for use in Homeland Security, Medical, Non-destructive Testing, and other markets includes a power supply, and a single x-ray tube. The X-ray tube includes two cathodes, and a single anode. The electrons from the cathodes travel predominantly along the axis of the x-ray tube, and impact the anode. The grid and/or focus coil direct the electrons so that electrons can pass by the cathode. The cathodes are kept at different potential, such that the tube can rapidly switch energies, and can rapidly switch output flux from each cathode.
