We describe the design of a proposed source of ultra-fast synchrotron radiation x-ray pulses based on a recirculating superconducting linac. The source produces x-ray pulses with duration of 20-50 fs at a 10 kHz repetition rate, with tunability from EUV to hard x-ray regimes, and optimized for the study of ultra-fast dynamics. A high-brightness rf photocathode provides electron bunches. An injector linac accelerates the beam to the 100 MeV range, and is followed by four passes through a 750 MeV recirculating linac. Ultrafast hard x-ray pulses are obtained by a combination of electron bunch manipulation, transverse temporal correlation of the electrons, and x-ray pulse compression. 20 fs EUV and soft x-ray pulses are generated in a cascaded free electron laser harmonic generation scheme. We describe technical developments in key areas including high rep-rate rf photocathode design, electron beam manipulation , collective effects, lattice design, rf systems for beam conditioning, x-ray beamline optics, and synchronization between experimental pump lasers and the x-ray pulse.
