Abstract:This invention relates generally to an improved method and to apparatus for controlling the initiation of X-rays.
(a). A primary object of the invention resides in the provision of an improved method for the reduction of the focal spot size within an X-ray tube which is adapted to deliver an X-ray burst of extremely short time duration.
(b). A further object is to improve the operation of an X-ray tube through improved control of the electron stream intermediate the cathode and the anode in a manner ultimately to decrease the effective target area.
(c). A still further object of the invention is to decrease the focal spot size within an X-ray tube pulsed in the time order of milliseconds or microseconds, including fractional portions thereof.
(d). Another object of the invention is to provide an improved apparatus for operating an X-ray tube during ex.tremely short time durations while confining electron flow therein intermediate the cathode and target to substantially linear paths.
(e). A still further object of the invention is to provide a method and apparatus for confining electron flow between the cathode and anode of a pulsed X-ray tube to convergent paths for the reduction of the focal spot size.
(f). Another important object of the invention resides in providing an X-ray tube adapted to be operated in response to a pulsed interelectrode current with a magnetic focusing means adapted to be operated in response to a pulsed current including electronic control for synchronizing electron beam flow within the period of maximum magnetic focusing flux.
(g). Other objects and advantages of the present invention Will become apparent to persons skilled in the art upon examination of the following description, the drawings and the appended claims.
