Jefferson Lab is planning a facility for studying ultrafast dynamical processes using a 1 kW average power IR/UV FEL, and a mode-locked Ti-sapphire femtosecond laser in the visible, combined with a 1 nm critical wavelength electron storage ring. Light pulses from the three sources will be synchronized at 125 MHz for pump-probe studies (including pump-pump-probe and pump-probe-probe options) in chemistry, physics, materials science, medicine and biology. The FEL operates with pulses as short as 300 femtoseconds (σ), which will provide the narrow bandwidth pump at high peak as well as average power. The FEL is currently operating and will soon be upgraded to operate at up to 10 kilowatt average power at an extended wavelength range from 300 nm to 10,000 nm. A compact superconducting storage ring, Helios-1, has recently been donated to Jefferson Lab that has a critical wavelength of 10 Å and is capable of storing currents up to 800 mA. In addition to providing spectroscopy capabilities, the storage ring will also support exploratory X-ray lithography R&D, including a precision stepper-aligner for training purposes. The facility, which is expected to become available in 2004, will be described and the capabilities detailed
