SUMMARY:Scientific advances at Tantalus\, world's first dedicated sync
 hrotron radiation facility\, and beyond\, Physics Department Colloquiu
 m\, Tai Chiang with intro by David Lynch (Iowa State)\, University of 
 Illinois at Urbana-Champaign
DESCRIPTION:Tantalus\, a 240 MeV electron storage ring\, began operati
 on in 1968 as the world's first dedicated synchrotron radiation user f
 acility. This revolutionary idea of using synchrotron radiation for br
 oad support of science and technology proved a resounding success\, an
 d it subsequently led to worldwide development of ever more powerful l
 ight sources for R&D. The main areas of research at Tantalus covered a
 tomic and molecular spectroscopy\, optical properties of solids\, and 
 electron spectroscopy (photoemission). Many of the early experiments w
 ere "the first\," focusing on source and detector development\, techni
 cal refinement\, and exploration using the newly available tunable VUV
  and soft x-ray radiation. Major breakthroughs encompassed high-resolu
 tion gas phase measurements\, band structure determination of solids\,
  core level spectroscopy\, surface chemistry\, photoelectron diffracti
 on\, many-body excitations\, etc. In this talk\, I will review some ke
 y ideas and developments at Tantalus that paved the way for modern res
 earch in a variety of novel materials and systems. I will also make a 
 few comments about the successor of Tantalus\, the 1 GeV storage ring 
 Aladdin\, which began in 1986 and ended operation in 2014\, where appl
 ications of synchrotron radiation including the IR spectral range cove
 red diverse topics including superconductors\, strongly correlated mat
 erials\, graphenes\, ultrasmooth thin films and epitaxial stacks\, top
 ological insulators\, bio and medical systems\, geological samples\, h
 istorical and artistic artifacts\, and extraterrestrial specimens. I w
 ill end with a brief perspective on the future of research using light
  source facilities.
