    Abstract: PURPOSE:To aim at expansion of an electron beam radiation area without any change a direction of X-ray generation by making a target in a rotating columnar form, rotating its rotary axis in titled mode against the direction of the electron radiation and moving it in the direction of axis center of the rotary axis. CONSTITUTION:A target 3 is formed columnar, in its circumference to be made freely rotatable by a rotation axis 4, the rotary axis 4 is set up as tilting against the direction of electron beam radiation from an electron gun 2 and also, the target 3 is made freely movable in a direction shown by arrow S along the axis center of the rotary axis 4. When the rotary axis is rotated under its state irradiated by electron beams, the electron beam radiation area is allowed to distribute at the peripheral side of the target 3. Further, an X-ray generation point P on the peripheral side of the target 3 is changed and electron beam radiation area is expanded by movement of the target 3 along the axis center of the rotary axis 4, but any direction change of X-ray radiation can not follow.

    Abstract: A radiation generating apparatus includes a target base 110, a target 120, a holding assembly 130 and an electronic beam generating device 140. The target is disposed on the target base. The holding assembly holds the target base. The electronic beam generating device is adapted to generate an electronic beam, wherein the electronic beam is emitted to the target to generate a radiation. The target, the holding assembly and the electronic beam generating device are located at the same side of the target base. The device may also be provided with a first driving unit 160 which is to adapted to drive the target base to move along the radial direction. The device may then have a second driving unit 132 and a rotation member 134, which are adapted to drive the rotational member and the target base to rotate along the axial direction.

    Abstract: A high flux X-ray tube anode target assembly (101). The assembly includes a support shaft (107) connected to a pivot assembly (109). The assembly further includes a movable anode target (105) having a target surface (106) disposed at one end of the support shaft. The target surface includes a single radius of curvature. The radius of curvature extends from a pivot point (110). The assembly also includes a drive member (119) operably arranged with respect to the support shaft to provide motion to the anode target. The assembly is configured to maintain a substantially fixed distance between the pivot point and the target surface.
