Abstract :
Based on the “QiangGuang-I” facility, a 1-m-long magnetically insulated transmission line (MITL) with a 2-cm anode-cathode gap was designed and experimentally studied. The experimental results show that with the load resistance of 2.07 , current loss along the 1-m-long MITL is negligible, and nearly all of the current loss occurs in the transition from conical disk to coaxial geometry or the output port of the line. At the same time, a 1-D circuit model was developed for the analyses of the MITL on the basis of the transmission-line code. By using this model, the experimental MITL was simulated, and pivotal parameters were estimated. Comparisons indicate that the simulation results agree to 5% within those of the experiments.
