A collaborative research effort was launched in 2000 between the Air Force Research Laboratory and Los Alamos National Laboratory to investigate the formation of high density field-reversed configuration (FRC) plasmas for the purpose of then adiabatically compressing them to a high energy density (HED) state. The goal of the experimental system developed through this collaboration was to enable a...
Summary form only given. The presence of plasma has long been suspected to be a major cause of gap closure in high power crossed-field diodes and HPM sources, even under the condition of magnetic insulation as in relativistic magnetrons. Our recent work [Lau et al., 2007] suggested that the presence of positive charge, anywhere in the diode gap, always increases the extent of the electron hub height...
We obtained full axial coverage radiography of a deformable contact imploding liner. This radiographic data indicates the feasibility of using a varying thickness in a long cylindrical solid liner, driven as a 12 megamp Z-pinch, to achieve factor- 16 cylindrical convergence, while using 8 cm diameter aperture electrodes. The Al liner was 30 cm long, with 9.78 cm inner diameter for its full length,...
