ABSTRACT
This femtosecond synchrotron radiation x-ray source, currently under
development at LBNL, is based on a flat-beam RF gun and a recirculating
superconducting linac that provides beam to an array of undulators
and bend magnets. X-ray pulse durations of <100 fs at a 10 kHz repetition
rate are obtained by a combination of electron pulse compression, transverse
temporal correlation of electrons and x-ray pulse
compression. With this ultra fast synchrotron radiation source it will
be possible to directly measure the motion of molecules and atoms in
very fast dynamic systems as well as to provide sufficient flux for
weak scattering systems.An overview of the project and some of the technical
challenges involved will be presented.
