Light source and accelerator physics research program at Duke university
The light source and accelerator physics research program at Duke Free-Electron Laser Laboratory (DFELL), Triangle Universities Nuclear Laboratory, is focused on the development of the storage ring based free-electron lasers (FELs), and an FEL driven state-of-the-art Compton gamma-ray source, the High Intensity Gamma-ray Source (HIGS). With a maximum total flux about 3 × 1010 γ/s and a spectral flux of more than 103 γ/s/eV around 10 MeV, the HIGS is the world's most intense Compton gamma-ray source. Operated in the energy range from 1 to 100 MeV, the HIGS is a premier Compton gamma-ray facility in the world for a variety of nuclear physics research programs, both fundamental and applied. In this paper, we will describe our ongoing accelerator physics and light source development program in the areas of the storage ring magnetic optics characterization and compensation, FEL physics, and development of gamma-ray beams in the higher energy range (100 to 158 MeV).
