The Duke FEL Storage Ring Light Sources

Abstract
The 1.1 GeV Duke storage ring dedicated to drive a variety of light sources ranging from mm-waves to gamma-rays, is in operation since November, 1994. The heart of the Duke facility - the OK-4 XUV FEL and its Compton gamma-ray source - are in operation since November 1996. The first user applications research using the OK-4 FEL started in December, 1997. In 1998, the OK-4 FEL lased in the deep-UV range from 217 to 256 nm in 1998. Starting September, 1998, the coherent deep-UV radiation is used for applications in cornea surgery, cell biology, surface physics, and nuclear physics. We are developing a number of beamlines and user stations for applications research utilizing the capabilities of the Duke Storage Ring FEL facility. The construction of two-story Keck Science Laboratory dedicated for user research is nearly finished. We plan to deliver first XUV and gamma-ray beams to the new facility by April, 1999. A number of projects are under way at Duke Free Electron Laser laboratory to extend the wavelength range of light sources to mm-waves and to hard-X-ray regions. In this talk we will report the present and future capabilities of the Duke Storage Ring FEL facility. We will summarize the parameters of the electron and optical beams and review the progress of the user program.
