The design concept of a puffed gas electromagnetic implosion plasma generator is briefly discussed. Experimental investigations of the feasibility of producing reasonably well defined cylindrical gas shells in an electrode gap are reported. In these investigations, an exploding plug puff valve developed by I. Henins and J. Marshall was used to puff gas into a 35 cm radius, 2.4 cm long electrode gap. Transient gas density measurements were made for A and Nitrogen puffing using 6AH6 fast response ionization gauges. Such measurements indicate that gas shells with mass and radial confinement suitable for electromagnetic implosion can be produced. Theoretical aspects of the gas puffing are also discussed. Theoretical considerations indicate that the experimental results obtained are reasonable but that nonuniform axial density distributions may be expected which might distort attempted implosions. Methods for reducing the axial nonuniformity are discussed.
