"P\u0159edneseno na konf.:2010 IEEE International Power Modulator and High Voltage Conference,Atlanta,US,23.-27.05.2010,str.172, :We have built two experimental apparatuses CAPEX and CAPEX-U as XUV sources which are based on the fast capillary discharge. On both these devices we have observed lasing at 46.9 nm (Ne-like Ar line). However, these devices are not only lasing at 46.9 nm, but they also use for testing a possibility of amplification at the wavelength below 20 nm, that have more practical applications. Nowadays, the fast high-current capillary-discharge experiments with nitrogen-filled capillary are in progress as well. In this paper the capillary pre-pulse current and its influence on initial conditions (pressure, amplitude, duration) will be studied with the help of spectroscopic measurements." . . .
