Abstract : Instrumentation for soft X-ray research is briefly described. Preliminary results are shown for several dispersing systems which have been found useful in the 10 to 100A region. Results from single crystals of group 1A salts of phthalic acid are discussed, and intensity measurements are reported. Other organic single crystals such as long chain derivatives of adipic acid are evaluated along with films of organic compounds prepared by the Blodgett-Langmuir technique. The efficiencies of the dispersing elements mentioned above are compared with commercial crystals such as mica, ADP, and EDDT. Performance of detectors for soft X rays is shown for flow proportional and Geiger counters, solid state silicon barrier detector, and a windowless resistance strip magnetic electron multiplier. The relative efficiencies of several photocathode materials for the latter detector are discussed. (Author)
