Long-implosion PRS experiments on Double-EAGLE

Summary form only given. Previous research on the high-power generators DM2, at Maxwell Physics International, and Saturn, at Sandia National Laboratories, has demonstrated that long-implosion (200-300 ns) PRS sources, both gas puff and wire load, can be sufficiently stable to produce well-assembled pinches and high-power radiation pulses of soft X-rays (1-4 keV). This has substantial implications for reducing the cost and risk of future higher current facilities (e.g. Decade Quad). To extend our knowledge and understanding of long-implosion sources, we are conducting a well-diagnosed series of experiments on long-pulse Double-EAGLE (4 MA at 200 ns). Results from Ar gas puffs, with various nozzles and valves, and Al wire arrays will be presented. Where possible, comparison with short-pulse results will be discussed.
