“…A converging shock would then propagate in a relatively low-density gas in front of the main shell and would cause a significant density and temperature increase on axis prior to arrival of the main shell. This is a possible explanation for the early formation of a dense on-axis column in experiments by Shiloh, Fisher, and Bar-Avraham (1979).…”

“…As shown in Fig. 6 for Case IVB, endloss without fusionproduct heating leads to a rapid collapse of the pinch and an accelerated burn, with the fusion rate, S N ex (1 -f B ) 2 as is shown in Fig. 8 for Case VIB under otherwise identical conditions.…”

“…The x-ray output, efficiency, and implosion instabilities of z-pinches depend on the history of the implosion. In the past, a single-frame Mach-Zehnder interferometer was widely used to measure the density distribution of a flow field such as a z-pinch plasma [4,5]. A series of shots was performed to obtain the time history of the plasma implosion.…”

A small neon gas-puff z-pinch device was constructed, and the plasma implosion and its radiation characteristics were studied experimentally . The plasma implosion was investigated using a three-frame Mach-Zehnder interferometer (TFMZI) that is capable of taking three pictures (5 ns exposure and 13 ns interpicture delay) within a single z-pinch shot. Thermopiles were also used in the experiments with the TFMZI to study the correlation between the total energy of x-ray emission and the plasma implosion. The ion beams from the z-pinch plasma were analysed using a compact Thomson spectrometer. Based on the experiments, the imploding velocity and electron density of the plasma shell were obtained, a conclusion that a nearly uniform and symmetric imploding plasma shell would emit a higher x-ray yield than an asymmetric one was drawn and the charge state resolved energy spectra of ion beams emitted from the z-pinch plasma were plotted.

Interferometry of a gas-puff z-pinch plasma

Abstract: A nitrogen laser interferometer is utilized to study the density profile of a gas-puff z-pinch plasma during the implosion stage and the final collapse. The density profile and the plasma stability as a function of the different parameters are reported.
