COBRA is designed to drive ~10 nH loads at 1 MA with 95–230 ns zero-to-peak pulses. It has been used for a high energy density (HED) experiments involving conical wire arrays, radial foils, laboratory plasma jets, magnetic reconnection geometries, X-pinches, and Z-pinches of cylindrical wire arrays, gas-puffs, and thin metal liners.  These experiments are diagnosed with an extensive set of diagnostics including, x-ray and visible imaging and spectrometry, gated CCD cameras, x-ray and visible streak cameras, Thompson scattering, laser interferometry and backlighting, and imaging refractometry.  PUFFIN should be available for ZNetUS users during the next round of funding and will deliver 700 kA in 1.5-2 microsecond pulses. This long pulse capability complements existing ZNetUS facilities and is ideal for studying fundamental plasma processes in quasi-steady state. Initial diagnostics include laser imaging (schlieren, shadowgraphy, interferometry, Faraday rotation imaging) and visible spectroscopy, with Thomson scattering on the way. https://puffin.ece.cornell.edu/
