Evolution on Z-pinch in argon-filled capillary

A capillary plasma Z-pinch as an alternative active medium of soft X-ray la sers was studied experimentally and theoretically. The theoretical analysis was based on the self-consistent solution of the so called "snow-plow" mod el of plasma pinch together with feeding double-resonance circuit. The calc ulated development of the current as well as the evaluated pinch time are i n good agreement with the measured. ones. The experimental pinch time was e valuated from the time-resolved measurement of broad band soft X-ray emissi on.
