SUPERLUMI: A high flux VUV spectroscopic device for luminescence measurement

A new experimental set up for time and spectrally resolved luminescence experiments on atoms, molecules and solids under state selective excitation with synchrotron radiation (SR) is described. A uniquely large spectral range of luminescence analysis from 50 to 1000 nm is covered by a combination of two monochromators. The central device is a specially designed VUV toroidal grating monochromator with an extremely large f-number 1:2.8 for a working range from 50 to 300 nm. Excellent agreement between calculated and measured performance of this instrument is found. (orig.)
