Předneseno na:12th International Conference on X-Ray Lasers 2010,Gwangju, Jižní Korea ,30.05.2010-04.06.2010Fast capillary discharge in nitrogen is studied as a source of incoherent monochromatic radiation in "water window" wavelength range. Discharge current amplitude 13.5 kA and half period 140 ns were used. Strong spectral line at 2.88 nm was detected with alumina capillary (0.165 cm radius 20 cm length) filled by nitrogen at initial molecular pressure 10 - 220 Pa. The observed spectral line corresponds to the quantum transition 1s2p->1s2 of helium -like nitrogen ions. Spatial and time evolutions of pinching plasma quantities corresponding to this experiment were modeled by means of 1d MHD code NPINCH. Detail kinetics of nitrogen ions in the plasma in the axial region was evaluated by the FLY code used as the post-processor. The evaluated spectra confirm the most intensive spectral line corresponding to the helium -like nitrogen ions quantum transition 1s2p->1s2.
