Optimum 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 کاملSteady-state radiation ablation in the wire-array Z pinch
The mass ablation phase of a wire-array Z pinch is investigated using steady-state r , simulations. By identifying the dominant physical mechanisms governing the ablation process, a simple scaling relation is derived for the mass ablation rate ṁ with drive current I, in the case where radiation is the primary energy transport mechanism to the wire core. In order to investigate the dependence of...

متن کاملAxial x-ray backlighting of wire-array Z-pinches using X pinches.
For the first time, a geometry has been developed to allow for an axial imaging system for wire-array Z-pinch experiments that produce high-resolution x-ray images. The new geometry required a significant redesign of the electrode hardware. Calibrated areal density measurements of the Z-pinch plasma including wire cores, coronal plasma, streaming plasma, and the precursor were obtained. The sys...
متن کامل250 kA compact linear transformer driver for wire array z-pinch loads
We present the application of a short rise ( 150 ns) 250 kA linear transformer driver (LTD) to wire array z-pinch loads for the first time. The generator is a modification of a previous driver in which a new conical power feed provides a low inductance coupling to wire loads. Performance of the new design using both short circuit and plasma loads is presented and discussed. The final design del...
