摘要：

The cathode sheath formation in a transient spatially small X-ray preionized high-pressure glow discharge with parameters typical for neon buffered XeCl lasers is investigated experimentally, Pictures of the light emission are taken with high temporal (approximate to 1 ns) and spatial (approximate to 25 mu m) resolution using a gated CCD-camera as well as a streak camera, Quantitative data on the spatial and temporal development of the sheath structure are given, The most prominent feature is an extremely fast formation of a thin and very bright cathode sheath at a time which could be time correlated with an accuracy of +/-0.2 ns with the discharge current. The results can be used to check numerical model calculations of the sheath formation.
