Lawrence Livermore National Laboratory LLNL is evaluating design alternatives to improve the voltage regulation in our Flash X-Ray FXR accelerator cell and pulse-power system. The goal is to create a more monoenergetic electron beam. When an electron beam crosses the energized gap of an accelerator cell, the electron energy is increased. However, the beam with the associated electromagnetic wave also looses a small amount of energy because of the increased impedance seen across the gap. The beam-induced voltage at the gap is time varying. This creates beam energy variations that we need to understand and control.
