An apparatus and method for magnetic control of an electron beam includes a control circuit having a first low voltage source and a second low voltage source. The control circuit also includes a first switching device coupled in series with the first low voltage source and configured to create a first current path with the first low voltage source when in a closed position and a second switching device coupled in series with the second low voltage source and configured to create a second current path with the second low voltage source when in a closed position. The control circuit further includes a capacitor coupled in parallel with an electron beam manipulation coil and positioned along the first and second current paths and a current source circuit electrically coupled to the electron beam manipulation coil and constructed to generate an offset current in the first and second current paths.

Apparatus and method for magnetic control of an electron beam

An apparatus and method for an electron beam manipulation coil for an x-ray generation system includes the use of a control circuit. The control circuit includes a first low voltage source, a second low voltage source, and a first switching device coupled in series with the first low voltage source and configured to create a first current path with the first low voltage source when in a closed position. The control circuit also includes a second switching device coupled in series with the second low voltage source and configured to create a second current path with the second low voltage source when in a closed position and a capacitor coupled in parallel with an electron beam manipulation coil and positioned along the first and second current paths.
