Abstract
We have developed a dual-plenum gas valve coupled to a double shell nozzle for the generation of "shell-on-shell" gas loads in z-pinch plasma radiatio n source experiments. The gas density profiles of the nozzles have been cha racterized with laser interferometry. This valve/nozzle combination has bee n successfully fielded on the Double-EAGLE and Saturn pulsed-power generato rs. The design and characterization of the shell-on-shell valve/nozzle are presented in this article. (C) 2000 American Institute of Physics. [S0034- 6748(00)04808-5].
