Future large-scale pulsed-power accelerators are commonly designed based on linear transformer driver (LTD) topology. With the number of gas switches being significant (~ 100000), switch prefire might be an inevitable malfunction in LTD accelerator. The transmission characteristics and its influences major components a multicavity module remain to investigated. In this article, mechanism fault voltage generation by inductive coupling effect magnetic core were thoroughly understood. It was...
In order to analyze the performance of a fast linear transformer driver (FLTD) in different states, we develop circuit model nonlinear magnetic core.

Linear transformer driver (LTD) technology allows a pulsed-power generator to be transportable due its salient features in compactness and modular design. To further reduce the footprint of an MA-class generator, nested transmission lines were designed tested for current adding four-stage gas-insulated LTD module. The adder assembly contained two modules that charged opposite polarities. Each module held cavities shared common electrode line with deionized water insulation. Post-hole...
