An experiment had been proposed to investigate a photopumped x-ray laser approach using a novel, high-density, laser heated supersonic gas jet plasma to prepare the lasant plasma. The scheme to be investigated uses the he-like sodium 1.10027 nm line to pump the He-like neon 1s-4p transition at 1.10003 nm with the lasing transitions between the n = 4 to n = 2,3 states and the n = 3 to n = 2 state at 5.8 nm, 23.0 nm, and 8.2 nm, respectively. The experiment had been proposed in 1990 and funding began in January 1991. After extensive preparations to perform the experiment on the GDL laser, a series of circumstances made it impossible to pursue the research over the past 5 years. These were (1) lack of access to the GDL laser and its eventual closing, (2) the inability to identify an alternate laser system with which to perform the experiment, and (3) the lack of problem relevancy after 5 years of delays. As a consequence, it has been decided not to pursue the research any further
