Direct comparison of pinch dynamics of noble gases (Neon, Argon, Krypton and Xenon)On Linear Transformer Driver CESZAR

Radiation plays an important role in the implosion dynamics of pinches. In order to understand the effect of radiation, we conducted a comparative study of annular liner gas puff Z-pinches using Ne, Ar, Kr, and Xe on the CESZAR Linear Transformer Driver (LTD) capable of producing ~500 kA current with a ~160 ns rise time. Diagnostic techniques implemented included a four-frame time-gated XUV pinhole camera and a two-frame schlieren imaging system enabling detailed visualization of the implosion dynamics and stability characteristics. Filtered X-ray pin diodes were also included to capture precise timing of the pinch and relative X-ray yield. The results show significant variations in stability and pinch dynamics as a function of atomic number of a gas. Detailed analysis will be presented at the meeting.
