A Plasma Lens for High Intensity Laser Focusing
A plasma lens based on a short hydrogen-filled alumina capillary discharge is experimentally characterized. For a plasma length of about 5mm, the focal length, measured from the plasma entrance, was ∼ 11 to 8mm for on axis densities of ∼ 2.5 to 5 ×1018cm−3, respectively. The plasma temperature away from the walls of the 1/2mm diameter capillary was estimated to be ∼ 8eV indicating that the plas...
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 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 کاملOptimum driving a Z-pinch for soft X-Ray lasers
A capillary plasma z-pinch as an alternative active medium of soft X-Ray lasers was studied experimentally and theoretically. The theoretical analysis was based on the self consistent solution of the so called “snow plow” model. The dynamics of pinched plasma is determined by the capillary parameters and by the time dependence of electrical current passing through it. The current time dependenc...
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...
