Modular Theta-pinch Experiment (MTX) expansion

The Modular Theta-pinch Experiment (MTX) at Los Alamos National Laboratory consists of multiple theta-pinch and transverse magnetic coils, each driven by several independently-triggerable capacitor/switch modules. This design enables straightforward expansion and reconfiguration to drive a wide range of experiments and has been used to explore the physics of high-density ionization and Field-Reversed Configuration (FRC) formation employing a variety of techniques. MTX is currently undergoing an expansion to incorporate additional theta pinch drivers, transverse field coils, and to increase the range of accessible driver voltages. An overview of the experiment and discussion of recent activities will be presented.
