X-ray spectroscopic methods were used to investigate the spatial distr
ibution of Z-pinch plasma parameters. Experiments were carried out on
the GAEL pulse line generator in Ecole Polytechnique (France) with dif
ferent types of load. Obtained results for the concentration of electr
ons and plasma temperature showed that higher plasma homogeneity was o
btained in experiments with complex load. Spectrograms demonstrate the
stabilization effect of the Al-jet.
