Abstract :
A capillary discharge apparatus for generation of XUV radiation is presented. Radiation is generated by Z-pinching plasma in 20 cm long ceramic capillary. Fast current pulse with amplitude of 15 kA and rise-time of 50 ns is used to generate this Z-pinching plasma. We observed Amplified Spontaneous Emission at 46.9 nm of 3p - 3s transitions of Ne-like argon ions at argon filling pressures of (10 - 25) Pa. The spectroscopic measurements showed amplification of two orders.
