Circuit modeling for magnetically insulated transmission lines on primary test stand

Primary test stand(PTS) is an underway highcurrent accelerator for Z-pinch experiment in CAEP. In the paper a circuit model have been developed, in which all the PTS's transmission line sections from water transmission lines, to vacuum insulator stack, to both outer and inner MITL, and eventually to a wire array load, have been treated as a total of 273 transmission line elements with different transit time and impedance, among which are 195 MITL elements. With the aid of a circuit model the performance of all these sections were predicted and discussed, including conducting current, interface voltage, loss current, flow impedance and grounded resistor of each MITL element, as well as the dynamic characteristics of the wire array load. The reliability and accuracy of all thes predicted r
