An account of the initial integration of photoemission and synchrotron radiation

The first energy-resolved photoemission experiments which used synchrotron radiation were performed on the Tantalus Storage Ring at the University of Wisconsin. The Ring was the first dedicated light source and during the winter of 1970–1971 D.E. Eastman and the author's groups carried out the initial experiments. Previously UV solid state experiments used the retarding-potential method developed by W.E. [Bill] Spicer at RCA and Stanford Univ. Laboratories. New instrumentation was needed. End stations were designed that utilized the double-pass cylindrical mirror electron energy analyzer [CMA]. A summary discussion of the history of the events that led to the first experiments are presented.
