Abstract
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.
