Předneseno na:37th International Conference on Vacuum UltraViolet and X-ray Physics, Vancouver,11.07.2010-16.07.2010 : Our aim is to develop a tabletop monochromatic incoherent water window radiation source based on the pinching capillary discharge in nitrogen. We have performed preliminary experiments with alumina capillary filled by nitrogen. Strong spectral line at 2.88 nm, corresponding to the quantum transition 1s2p -> 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 Z*-engine code. Computer and laboratory 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.
