Abstract
Abstract 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* 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
109 words
A method of effecting the efficient distribution of available ionizing energy from an electron beam produced in an evacuated container and directed toward at least a pair of elongate electron permeable windows arranged in a side-by-side spaced apart configuration in a wall of said container, said method comprising the steps of: scanning said beam over a predetermined time period along the length of one of said windows, instantaneously directing said beam from said one window to the other of said windows, scanning said beam over a predetermined time period along the length of said other window, and instantaneously directing said beam from said other window to said one window.
Claim 2
Independent Claim
109 words
A method of effecting the efficient distribution of available ionizing energy from an electron beam produced in an evacuated container and directed toward at least a pair of elongate electron permeable windows arranged in a side-by-side spaced apart configuration in a wall of said container, said method comprising the steps of: scanning said beam over a predetermined time period along the length of one of said windows, instantaneously directing said beam from said one window to the other of said windows, scanning said beam over a predetermined time period along the length of said other window, and instantaneously directing said beam from said other window to said one window.
Claim 3
Dependent Claim
17 words
The method of claim 1, further comprising the step of: repeating the steps recited in Claim 1.
Claim 4
Dependent Claim
39 words
The method of claim 1, wherein beam scanning along the length of said one window is a first direction and beam scanning along the length of said other window is in a second direction opposite to said first direction.
Claim 5
Independent Claim
255 words
A method for increasing the output of an electron accelerator capable of producing an electron beam within an evacuated container, said beam being directed at a pair of elongate electron permeable windows arranged in a side-by-side spaced apart configuration in a wall of said container, said accelerator including a first pair of beam scanning coils positioned on opposite sides of said electron beam for scanning said beam along a path parallel to a first axis and a second pair of beam scanning coils positioned on opposite sides of said electron beam for scanning said beam along a path parallel to a second axis, each one of said second pair of coils being spaced 90* from each one of said first pair of coils such that said second axis is normal to said first axis, said method comprising the steps of: establishing a first varying current condition in said first pair of coils and a first constant current condition in said second pair of coils, thereby scanning said beam in a first direction parallel to said first axis along the length of one of said windows; instantaneously establishing a second constant current condition in said second pair of coils, thereby directing said beam in a path parallel to said second axis to the other of said windows; and establishing a second varying current condition in said first pair of coils while maintaining said second constant current condition in said second set of coils, thereby scanning said beam in a second direction parallel to said second axis.
Claim 6
Independent Claim
255 words
A method for increasing the output of an electron accelerator capable of producing an electron beam within an evacuated container, said beam being directed at a pair of elongate electron permeable windows arranged in a side-by-side spaced apart configuration in a wall of said container, said accelerator including a first pair of beam scanning coils positioned on opposite sides of said electron beam for scanning said beam along a path parallel to a first axis and a second pair of beam scanning coils positioned on opposite sides of said electron beam for scanning said beam along a path parallel to a second axis, each one of said second pair of coils being spaced 90* from each one of said first pair of coils such that said second axis is normal to said first axis, said method comprising the steps of: establishing a first varying current condition in said first pair of coils and a first constant current condition in said second pair of coils, thereby scanning said beam in a first direction parallel to said first axis along the length of one of said windows; instantaneously establishing a second constant current condition in said second pair of coils, thereby directing said beam in a path parallel to said second axis to the other of said windows; and establishing a second varying current condition in said first pair of coils while maintaining said second constant current condition in said second set of coils, thereby scanning said beam in a second direction parallel to said second axis.
Claim 7
Dependent Claim
15 words
The method of claim 4, wherein said first direction is opposite to said second direction.
Claim 8
Dependent Claim
53 words
The method of claim 4, further including the further steps of instantaneously re-establishing said first constant current condition in said second set of coils, thereby redirecting to said one window said beam in a path parallel to said second axis and terminating the second varying current condition in said first pair of coils.
