“…The transient characteristics of this circuit gave us an idea about discharge current amplitude, quarterperiod, etc. Later on comparison [9] of these transient characteristics with experi- mental curves enabled us to find more appropriate values of elements of this circuit (fortunately, corrections turned to be very small) for better agreement (fitting procedure). Therefore, at present the CAPEX equivalent circuit is realistic enough to use its transient characteristics for further conclusions.…”

One of the problems that have to be taken into account during the technical realization of the pulse high-current capillary discharge is the life-time of the applied capillary. We are presenting here results of our investigation of alumina-capillary inner-surface after several hundred shots in the CAPEX device. It was found that capillary life-time is limited by a rugged glassy layer forming on its inner-surface. The layer seems to be formed by partially melted material of the capillary and has a very remarkable structure. Its motifs and depths change with the distance from the capillary-end. Besides detailed microphotographs we are presenting our working hypotheses that suggest explanation of layer formation.

“…Modern sources of radiation usually work on single and double forming lines, but capillary loads possess, as a rule, a great external diameter and hence, a large input inductance. It allows the electric field to penetrate inside the capillary and break down long gas intervals Manuscript [2], but long lines still work as fast capacitors; thus, the question of matching remains unanswered.…”

Results of research on fast discharges in a lowinductive capillary tube with a close-placed return coaxial conductor are presented. Main attention was given to the study of questions that are connected with matching the processes that occur in a generator of high-voltage pulses, transporting line, and capillary tube. The main purpose of this matching was optimization of transfer and transformation of energy, which focuses on effective obtainment of nonequilibrium plasma.

“…We assembled the CAPEX device that turned out to be in a good agreement with the numerical simulations [1]. The CAPEX apparatus was modified in 2003, mainly the region of its spark gap and the capillary part.…”

We have studied high-current capillary discharge as a prospective XUV laser source since 1998. We have built two experimental devices CAPEX and CAPEX-U. On both these devices we have observed the very strong amplification of neon-like argon line at 46.9 nm, which corresponds to laser transition. Recently high resolved spectra were obtained with the help of McPherson spectrometer as well as a spherical Si/Sc multilayer mirror was used to focus laser pulses generated by a 46.9-nm capillary-discharge amplifier. The latest experimental results are presented in this paper.
