X-ray imaging indicates magnetized liner inertial fusion (MagLIF) stagnation columns have a complicated quasi-helical structure with significant variations in x-ray brightness along the column. In this work, we describe MagLIF experiments aimed at controlling these structures by varying initial geometry and composition. First, aspect ratio of liner, demonstrate change that is consistent helical magneto Rayleigh–Taylor (MRT) instabilities feedthrough from outer-to-inner surfaces liner....
Magnetized liner inertial fusion (MagLIF) experiments have demonstrated fusion-relevant ion temperatures up to 3.1 keV and thermonuclear production of 1.1 × 1013 deuterium–deuterium neutrons. This performance was enabled through platform development that provided increases in applied magnetic field, coupled preheat energy, drive current. Advanced coil designs with internal reinforcement an increase from 10 20 T. An improved laser pulse shape, beam smoothing, thinner entrance foils increased...
We report on a series of Magnetized Liner Inertial Fusion (MagLIF) experiments conducted the Z pulsed power facility that utilized high aspect ratio (ratio outer radius to wall thickness) liners with dielectric coatings and low-mix laser preheat configurations. The consisted an 10.6 beryllium tube coated 75 μm epoxy outside have been shown maintain better implosion stability than uncoated demonstrated consistent stagnation performances in previous [Ampleford et al., Phys. Plasmas 31, 022703...
The inductively driven transmission line (IDTL) is a miniature current-carrying device that passively couples to fringe magnetic fields in the final power feed on Z Pulsed Power Facility. IDTL redirects small amount of Z’s energy along secondary path ground, thereby enabling pulsed diagnostics be parallel with primary load for first time. experiments and modeling presented here indicate IDTLs operate non-perturbatively they can draw excess 150 kA current, which enough drive an X-pinch...
Argon gas puff implosions have been found to be an extremely efficient source of K-shell x-rays (3-4 keV) on the Z pulsed power facility at Sandia National Labs. producing over 300 kJ emission in double-shell experiments. Experiments Double Eagle [1] and Saturn [2] previously that adding a central jet mass their configurations increased yield substantially.This presentation will describe recent experiments investigated effect doubleshell puffs plasma conditions. The was added two...
We describe a direct absolute magneto-optical approach to measuring the magnetic field driven by long pulse width (>5 ms) and high electrical current (∼kA) in solenoidal coil. The are among most important operating parameters lightning research power distribution essential understanding properties of radiation output pulsed energy accelerators as well other platforms. However, accurately these fields currents using conventional diagnostics is difficult due strength ionizing...
