"The aim of the proposed grant is focused onto the further construction and optimization of the experimental set-up built for generation of intense spontaneous and coherent soft x-ray radiation. In this kind of sources a hot and highly ionized plasmacolumn is produced by the electric current flowing axially through a low-pressure gas filled capillary channel. The plasma temperature and consequently the stage of ionization of the elements present in the capillary filling, is the fast radialcompression (z-pinch) due to the magnetic field created by the current itself. The experimental apparatus, which has been built in wide international cooperation produces current pulses that are sufficient for effective compression of the plasma column.The main goals of our investigation involve optimization of the experimental set-up, measurements of the pinch-dynamics, improvement and applications of the capillary z-pinch model and investigation of a possible application of metal-vapor as a lasing"@en . .
