“…Further, as predicted in the theory leading to Eqs. (1) and (2) when the line is mismatched [11], some bandwidth broadening may result and tracking will become less accurate. Just beyond the base of the pulse in Fig.…”

“…For a measured rise time of approximately 6 ns, the bandwidth of the Bournlea pulse is about 58 MHz [11]. The bandwidth of the Bournlea pulse exceeds the bandwidth of the connecting load circuit by about a factor of 1.1 implying that the calibration circuit amplitude differences and pulse broadening should be expected but this is not due to the limitations of the EM-dot.…”

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing this collection of information.

Significantly strong pinches have been recorded. 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/time-scale 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. Verification studies are underway. Results are reported.
