Capillary discharge plasmas can serve for recombination-pumped x-ray lasers. We present time-resolved x-ray spectra and density measurements of a nitrogen capillary discharge z-pinch plasma. We use a free-standing transmission grating spectrometer and a gated MCP camera. This is the first time both K-shell and L-shell line emission of the nitrogen plasma are recorded simultaneously. Comparison of...
The recombination pumping scheme for soft X-Ray lasers has better energy scaling, than the collisional-excitation pumping scheme. Implementation of an H-like 3→2 Nitrogen recombination laser, at »∼13.4nm requires initial conditions of at least 50% fully stripped Nitrogen, kTe∼140eV and electron density of ∼1020cm−3. In order to reach population inversion, the plasma cooling to below 60eV should be...

Implementation of an H-like 3 → 2 Nitrogen recombination laser, at λ∼13.4 nm requires initial conditions of at least 50% fully stripped Nitrogen, kTe∼140eV and ne∼1020cm−3. In order to reach population inversion, the plasma cooling to below 60eV should be faster than the...
