Determination of line mass density for the gas load of a gas puff Z-pinch

For a particular pulsed-power generator, i.e., fixed pinch current as well as its rise time, the z-pinch load (initial radius r0 and line mass density m0 ) should be optimized to maximize the x-radiation. The radial density profile of the gas load produced by a supersonic nozzle used in gas puff z-pinch was measured with a miniature fast ionization gauge and it yields a line mass density of 43 μg/cm that is in agreement with the nozzle design.
