Claim:
1. A method of generating a plasma, comprising the steps of: ejecting a neutral gas from a Laval nozzle radially over a shock coil having an annular disc shaped body bounded by an outer ring formed about an outer periphery of the body and an annular hub formed about an inner periphery of the body and a coil of parallel wound wires attached to a face of the body, wherein the nozzle has an annular disc-shaped nozzle body coupled about an inner periphery of the nozzle body to the hub and forming with the hub about an outer periphery of the nozzle body a radially oriented annular nozzle outlet positioned adjacent the inner periphery of the body of the shock coil, wherein the neutral gas is ejected from the nozzle outlet in a radial direction parallel to the disc shape body to emanate over the coil of parallel wound wires, and energizing the coil windings to ionize the neutral gas into a plasma and eject the plasma from the shock coil.
