Claim Text:
1. A system for controlling an electron beam in an x-ray source, the system comprising: at least one of (i) a first switching unit having a voltage source and a pair of switches connected in series and configured to switch between open and closed positions to change an output voltage to one of engage or bypass the voltage source, or (ii) a second switching unit having a voltage source, and a first pair of switches connected in series and a second pair of switches connected in series, the first and second pair of switches connected in parallel, and wherein the first and second pairs of switches are configured to switch between open and closed positions to engage or bypass the voltage source to an output voltage; and at least one of a third switching unit having an amplitude controllable voltage source with controllable amplitude, a first pair of switches connected in series and a second pair of switches connected in series, wherein the first and second pair of switches are connected in parallel, and wherein the first and second pairs of switches are configured to switch between open and closed positions to engage the amplitude controllable voltage source with as a positive voltage, a negative voltage or to bypass the amplitude controllable voltage source, wherein the first, second, and third switching units are connected in series and the output voltages generated by the first, second and third switching units define a voltage profile for controlling an electron beam in an x-ray source.
