Three-dimensional numerical simulation of the single-channel pulsed-power vacuum device

A single-channel pulsed-power vacuum device is studied. Based on the platform of CHIPIC, the limitation of memory and computation speeds of a single computer is broken through by the method of parallel computation of multi-computers. For the model of the whole device, the models of the parts of feed-in, convergence and transmission in the single-channel pulsed-power device are built, and the parameters are set up. The obtained voltages between the cathode and anode, as well as the currents of the cathode and the anode using the proposed models are in accordance with the theoretical ones. The single-channel pulsed-power vacuum device also can retain magnetically insulated and achieve the function of convergence of power. This shows the feasibility of the single-channel pulsed-power vacuum device.
