    Fast capillary discharge in nitrogen is studied as a source of incoherent monochromatic radiation in "water window" wavelength range. Discharge system with current amplitude 13.5 kA and half period 140 ns was designed, realized and modeled. Strong spectral line at 2.88 nm corresponding to the quantum transition 1s2->21s2 of helium -like nitrogen ions was detected. The initial pressure nitrogen in the alumina capillary was varied from 10 to 220 Pa. Peak value of the line intensity at about 50 Pa was found and proved by the computer modeling.
