The authors are using the 2-D TWOQUICK simulation code to study a system consisting of a voltage adder, a long magnetically-insulated transmission line (MITL), and a large-inductance load which includes a conducting foil (short circuit). The object of this work is to produce a voltage pulse of typically 10 MV and several hundred ns which travels down a MITL of about 10 meters length and 5--10 ohms vacuum impedance, and then couples efficiently to a load of a few hundred nH inductance. They discuss modeling issues such as the use of simple transmission lines for parts of the system, and methods for representing the load. Important physics issues include voltage-pulse erosion in long MITLs, effects of reflected waves from the highly overmatched load impedance, and energy fraction delivered to the load. They calculate electron losses in all parts of the system. Parameter variations of interest include input voltage waveform, adder geometry, MITL length and impedance, and loaded configuration and inductance. Comparisons with circuit models (SCREAMER) will be shown.
