| Abstract | The capillary discharge soft X-ray laser is a promising scheme with its long capillary plasma column that is efficiently generated by the fast current pulse of about several 10s ns. In this study, the possibility of a recombination soft X-ray laser will be discussed in anticipation of realizing a 13.4 nm H-like N EUV laser. Evolution of EUV emission from nitrogen plasma with number density of 10 18 cm -3 was measured and analyzed with MHD calculation. Comparing the experimental and the calculation results, it is considered that in order to initiate the collisional ionization effectively in a few ns and to obtain many fully-stripped nitrogen ions enough for lasing, much higher electron number density is required. The possibility of realizing a recombination soft X-ray laser pumped by the capillary discharge is discussed. |
