Abstract:
The Duke FEL lab operates a unique UV/VUV
storage ring FEL and an FEL driven nearly
monochromatic, highly polarized, high
intensity Compton gamma-ray source. The Duke
storage ring light source is undergoing
several phases of upgrade in order to
significantly improve its light source
capabilities and performance. The recent
upgrade in 2004 included an upgrade of the RF
system with a high-order mode damped RF
cavity and a new 34 meter long straight
section lattice designed to host new FEL
wigglers. This upgrade was completed in
August 2004, followed by the storage ring and
light source commissioning. This paper
provides an overview of this upgrade project
and reports the commissioning experience of
the Duke storage ring and light sources.
