Electrical Parameters of High Current Capillary Discharge Device

The CAPEX-U (capillary experiment -upgrade) apparatus has been developed as an XUV source based on high-current capillary discharge. Our main motivation for building such a new device was to create the XUV source with amplification of spontaneous emission at shorter wavelengths (below 20 nm), which have more practical applications. The preliminary experimental results of the assembled apparatus were obtained, especially the capillary current signal, and the time development of the pulse-forming-line voltage. The comparison of these experimental results with calculated/predicted values is reported in this paper as well
