Equivalent circuit modeling of space charge dominated magnetically insulated transmission lines

We have developed a new equivalent circuit model for space charge dominated MITLs(Magnetically Insulated Transmission Lines). MITLs under high power operation are dominated with space charge current flowing between anode and cathode. Conventinal equivalent circuit model does not account for space charge effects on power flow. To discuss the power transportation through the high power MITLs, we have modified the model. With this model, we can estimate the effects of space charge current on the power flow efficiency, without using complicated particle code simulations.
