Population inversion is expected on 2p-2s transitions in neon-like germanium in the 60-80 A region. The feasibility of observing gain on these transitions is explored. Soft x-ray amplification is collisionally excited. Ne-like Ge plasmas has been extensively studied in a number of laboratories. Gains in excess of 4cm-1 have been reported for the 3p-3s transitions and significant gains have been inferred over a wide range of irradiance conditions. In our laboratory we have made use of a novel focusing arrangement that employs a segmented wedge array to overlap several line foci to produce a more uniform linear plasma.
