K-shell radiation of multiple shell gas puff at microsecond implosion times

This paper presents the results of experiments with a multiple shell gas puff Z-pinch at microsecond implosion times, performed on the GIT-12 generator. Two concentric annular gas jets had diameters of 16 cm (outer shell) and 8 cm (middle shell). The inner on-axis solid fill had a diameter of 2.2 cm. The plasma stability and the neon and argon K-shell yields are discussed.
