Abstract :
This paper describes the characteristics of the EUV light source based on z-pinch discharges, which is driven by a low inductance pulsed current generator. The driving circuit with an inductance of 30 nH is capable of delivering the current of 34 kA in 110 ns to the z-pinch load. The z-pinch xenon plasmas are produced in the ceramic tube with the dimension of 3 or 5 mm in diameter and 5 mm in length. According to plasma dynamics observed by a fast framing camera, there are two radiation modes, one is dynamic and the other is quasistatic. Plasma behaves more dynamically with larger diameter discharge tube. The EUV emission from the z-pinch plasma was characterized with respect to spectrum and in-band EUV energy (13.5 nm, 2% bandwidth) as well as temporal behavior of the emission. Presently the maximum in-band EUV energy is 11 mJ/sr in the direction of 15 degree off-axis
