Dynamics of a capillary discharge x-ray laser

In this work we present the results of a numerical investigation of the MHD, atomic and amplification properties of a capillary discharge collisional soft x-ray laser. The comparison of the results of the developed model with the experiment reveal good timing, correct laser pulse duration and temporal features of the amplified line that are similar to those observed in the experiment. Also an encouraging correlation of the laser output angular distribution was obtained. The computed variations of the 3p-3s J equals 0 - 1 ArIX lasing line intensity with discharge parameters have been compared to experiments and show good agreement.
