Experimental Results from SHIVA Star Vacuum Inductive Store/Plasma Flow Switch Driven Implosions
Abstract
Using a 1313 microF, 3 nanohenry, 120 kV, 9.4 MJ SHIVA Star capacitor bank, we have performed vacuum inductive store/plasma flow switch {PFS) driven implosions of low mass {200-400 microg/cm2 ) cylindrical foil liners of 2 cm height and 5 cm radius. This technique employs a coaxial discharge through a plasma armature, which stores magnetic energy over 3 to 4 micros and rapidly switches it to an imploding load upon exiting the plasma armature from the coaxial gun muzzle. The current transferred to the load by the PFS has a rise time of less than 0.2 micros. With 5 MJ stored energy, we have driven fast liner implosions with a current of over 9 Megamperes, obtaining an isotropic equivalent 2.7 Terawatt, 0.5 Megajoule X-ray yield.
