Long implosion wire array experiments on the 8-MA Saturn and 20-MA Z accelerators

Summary form only given, as follows. The quest to reduce the complexity, cost and risk of higher current accelerators drives the need for implosion times that are longer than the canonical 100 ns of present waterline generators. Experiments have been performed at 100 to 200 ns implosion times on the 10-MA Saturn and the 20 MA Z accelerators. These experiments have shown that 7 to 10 ns FWHM pulses can be produced even at the longest implosion times. The experimental data will be presented along with calculations which indicate that stability, uniformity and plasma opacity are critical to determining the radiation efficiency of these implosions.
