Circuit modeling techniques applied to ZR

We present an overview of a detailed transmission-line circuit model of the refurbished Z accelerator (ZR). We also present comparisons of the model's calculations to data taken on ZR shots with short circuit loads (shots 1780 and 1852) and wire-array z-pinch loads (shots 1785 and 1896). The circuit model includes a 2-D network of transmission lines that model ZR's output lines and water convolute. The development of the 2-D network is discussed along with benchmarks to a 3-D LSP-based model.
