Numerical Simulation of the Common Vacuum Diode Load of “Gamma-4” Facility

The computational optimization of the common vacuum diode load design for “Gamma-4” electrophysical facility has been performed. The criterion of the optimization process was increasing the efficiency of energy and power transmission from accelerating modules to the load. It is shown that the impedance of the diode can be decreased to the required value ~0.7 Ohm (matched mode). According to the results of simulation it should lead to the rise of energy and power transmission efficiency by ~30% as compared with original design of the load.
