Paper Abstract

We present a small laser facility set up to calibrate and check X-ray instrumentation. The laser is a 4J-4ns neodymium YLF laser working at 1.053 gm and 0.53 gm with 50% efficiency conversion. We present X-ray pinhole images of Al and Copper created plasmas using different filters to obtain radiation from 1 to 2 keV. We present also V-UV images at different wavelengths from 100 to 300 ang. showing the large spectral range emissibity of the plasma used as source. In a further step crystal spectrograph and grating spectrograph will be set up around this source to select narrow band emission and to check for example the reflectivity of multilayered mirrors, the spatial resolution of V-UV objectives as Schwarzschild microscopes.
