Presented are voltage measurements taken near the load region on the Z pulsed-power accelerator using an inductive voltage monitor (IVM). Specifically, the IVM was connected to, and thus monitored the voltage at, the bottom level of the accelerator

Eighty years ago, it was proposed that solid hydrogen would become metallic at sufficiently high density. Despite numerous investigations, this transition has not yet been experimentally observed. More recently, there has been much interest in the an

High power microwave (HPM) sources based on the backward-wave oscillator (BWO) have been investigated for the past two decades primarily because of their potential for very high efficiency (15 to 40%) operation. Several different effects have been pr

Backward-wave oscillators (BWO) have long been used as voltage-tunable signal sources, and more recently as high-power microwave (HPM) sources. The frequency at which a BWO oscillates is commonly viewed as being determined by the circuit geometry and

The Air Force Research Laboratory RKO source has recently demonstrated the ability to convert electron beam power to RF power until the termination of the electron beam pulse, achieving a power of 1.5 GW at an energy of 170 J. These results represent

An analysis of the stability of magnetically insulated ion diodes is presented that includes electromagnetic perturbations both parallel and perpendicular to the applied magnetic field, and is fully relativistic. The theory represents a generalizatio

Recently, there has been a tremendous increase in the number of identified extrasolar planetary systems. Our understanding of their formation is tied to exoplanet internal structure models, which rely upon equations of state of light elements and com
