Abstract This grant aided in the design, construction, and operation of the UNLV Non-Equilibrium Plasma Pinch (NEPP) to be used for the study of basic research on plasma cathodes for high power microwave sources. Significantly strong pinches have been recorded experimentally. A UNLV patent pending beam management device was conceived, developed, and built to focus high energy, large electron population beams without the aid of an external magnetic field. Further, a technique was theoretically and experimentally developed to calibrate the UNLV patented EM dots used to measure time varying electric and magnetic field signatures simultaneously at one point in space in support of pinch experiments. A multiple space/timescale technique based on a multiple fluid approach has been developed to study non-equilibrium plasma pinch physics. Non-equilibrium zero order expressions have been established laying the foundation for higher order effects based on the existence of a sheet current plasma sheath. Three high school teacher summer research experiences were funded in support of basic plasma cathode research. Their equilibrium plasma discharge studies suggest a pinch mechanism responsible for the stable pinches observed in their experiments. This has lead to theoretical and experimental equilibrium pinch studies performed in parallel with the non- equilibrium studies.
