Z-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 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...
متن کاملIon temperature and hydrodynamic-energy measurements in a Z-pinch plasma at stagnation.
The time history of the local ion kinetic energy in a stagnating plasma was determined from Doppler-dominated line shapes. Using independent determination of the plasma properties for the same plasma region, the data allowed for inferring the time-dependent ion temperature, and for discriminating the temperature from the total ion kinetic energy. It is found that throughout most of the stagnati...
متن کاملIon-kinetic-energy measurements and energy balance in a Z-pinch plasma at stagnation.
The ion-kinetic energy throughout K emission in a stagnating plasma was determined from the Doppler contribution to the shapes of optically thin lines. X-ray spectroscopy with a remarkably high spectral resolution, together with simultaneous imaging along the pinch, was employed. Over the emission period, a drop of the ion-kinetic energy down to the electron thermal energy was seen. Axially res...
متن کاملElectron density and ionization dynamics in an imploding z-pinch plasma
The time-dependent radial distributions of the electron and ion densities during the implosion phase of a gas-puff z-pinch plasma are determined from measurements of continuum radiation, as well as time-dependent collisional-radiative analysis of the observed particle ionization history in the plasma. It is shown that during the 140-ns-long time interval close to the end of the 620-ns-long impl...
