FEL Research and Development at the SLAC Sub-Picosecond Photon Source, SPPS
- SLAC
An upgrade project to the SLAC linac allows ultra-short electron bunches to be interleaved with the routine high-energy physics program operation, for use with an undulator to produce short-pulse, high-brightness x-rays. The linac upgrade comprises of the installation in the summer of 2002 of a bunch compressor chicane of similar design to the Linac Coherent Light Source (LCLS) project. A final compression stage in the high-energy Final Focus Test Beam (FFTB) line compresses the 28 GeV, 3.4 nC electron bunch to 80 femtoseconds fwhm, where a 5 m section of undulator (K=4.45) will produce 1.5 {angstrom} x-rays with 3*10{sup 7} photons per pulse and a peak brightness of 4*10{sup 24} photons mm{sup -2} mrad{sup -2} s{sup -1} (0.1% BW). The facility will allow us to test the dynamics and associated technology of bunch compression and gain valuable experience for the LCLS using the SLAC linac. New ultra-short electron bunch diagnostic techniques will be developed hand in hand with the same ultra-fast laser technology to be used for LCLS. Issues of high peak power (27 GW) x-ray transport and optics can be addressed at this facility as well as pump-probe and ultra-fast laser timing and stability issues.
