METHOD FOR INCREASING THE OUTPUT OF AN ELECTRON ACCELERATOR

摘要

A method of increasing the energy output of an electron accelerator by scanning the electron beam produced in the accelerator in a manner so that excessive heat build-ups do not occur at the electron permeable window structure through which the beam passes to exit the accelerator. This method is used in conjunction with an accelerator having at least two elongate, electron permeable windows arranged in a side-by-side orientation and scanning coils allowing the beam to be scanned parallel to at least two, perpendicular axes. The method provides that the beam is scanned along the length of a first of the windows in a first direction and then instantaneously is scanned laterally to the second of the windows. The beam then is scanned along the length of the second of the windows in a second direction 180 DEG from the first direction. A return of the beam to its original position is accomplished as the beam then is scanned laterally and instantaneously a second time such that it again is directed at the first of the windows. Unlimited repetition of these scanning steps is possible.
