    Our aim is to develop a tabletop monochromatic incoherent water window radiation source based on the pinching capillary discharge in nitrogen. We have performed experiments with alumina capillary filled by nitrogen. Strong spectral line at 2.88 nm, corresponding to the quantum transition 1s2p→1s2 of the helium-like nitrogen ions, was observed. Spatial and time evolutions of pinching plasma quantities as well as the water window emission were modeled by means of RHMD code Z*. Computer and experimental results correspond each other. Computer optimization of the device has been done by varying capillary geometry, charging voltage and initial pressure. Reasonable capillary shortening has been suggested.
