Measurements of beam optical characteristics of neon-like germanium x-ray laser

The spatial profiles in the horizontal and vertical direction of lasting line intensity of neon-like germanium were measured. For a 20 mm long plasma 20 μm lateral dimension, the main beam in the horizontal direction is d to exhibit an angular divergence of 12 mrad with a offset displaced 8 from the plasma axis and the beam angular divergence in vertical direction is about 22 mrad. In addition, the characteristic of beam optics of the double pass amplification was diagnosed using a Mo/Si multilayer mirror
