The Sheared Flow Stabilized Z-Pinch
The stabilizing effect of a sheared axial flow is investigated in the ZaP Flow Z-pinch experiment at the University of Washington. Long-lived, Z-pinch plasmas are generated that are 100 cm long with a 1 cm radius and exhibit gross stability for many Alfvén transit times. Experimental measurements show a sheared flow profile that is coincident with the quiescent period during which magnetic fluc...
متن کاملEvidence of Flow Stabilization in the ZaP Z Pinch Experiment
The stabilizing effect of an axial flow on the m = 1 kink instability in Z pinches has been studied numerically with a linearized ideal MHD model to reveal that a sheared axial flow stabilizes the kink mode when the shear exceeds a threshold. The sheared flow stabilizing effect is investigated with the flow-through Z pinch experiment, ZaP. An azimuthal array of surface mounted magnetic probes l...
متن کاملZ-pinch Discharge in Laser Produced Plasma
Z-pinch effects in a laser produced aluminium plasma were investigated with a relatively low current fast coaxial electrical discharge. The ion flux in the laser produced plasma (LPP) was monitored with a Langmuir ion probe and the line density was controlled by using an aperture to select the portion of the LPP which enters the discharge cell. The Zpinch dynamics were recorded using time-resol...
متن کاملA Detailed Postprocess Analysis of an Argon Gas Puff Z-pinch Plasma Using SPEC2D
A postprocess analysis of a single time frame hydrodynamic profile from the PRISM two-dimensional MHD simulation of an argon gas puff Z-pinch plasma experiment on Double-Eagle generator at Physics Internationals, Co. is presented. In addition, spatially resolved emission spectra and filtered (Kand L-shell radiation) x-ray pinhole images, generated using the SPEC2D code, are examined toward the ...
متن کاملLaboratory Modeling of Meteorite Impact Craters by Z-pinch Plasma
Desai, et al. [1] simulated microparticle lunar impact craters using laser impacts. They produced crater diameters of several hundred μm in Al. Ford [2] made observations about lunar craters simulated by spark-machining on metal. These were also very small scale craters. This work expands the size of simulated impact craters from their sub-millimeter craters to craters over a centimeter and exp...
