Z-PINCH OF A MULTIWIRE LINER SURROUNDED BY AN OUTER GAS SHEATH

In experiments with the GIT-4 device, a combined load was used to incr ease the K-line radiation yield; as a result, the intensity of X-ray e mission was doubled. For a liner current of 1.5 MA, in the quantum-ene rgy range from 1.5 to 2 keV, a radiation power of 100 GW was obtained. As a result of the use of a gas sheath for sharpening the current fro nt, the temperature of the aluminum multiwire liner plasma increased f rom 0.8 to 1.2 keV, and the plasma homogeneity improved considerably. The results of one-dimensional magnetohydrodynamic simulations taking into account the radiative effects and anomalous plasma resistance are presented.
