A Sub-Picosecond Photon Pulse Facility for SLAC
It is possible to generate very bright sub-picosecond pulses of spontaneous x-ray radiation utilizing the electron beam from the SLAC linear accelerator and an undulator. The present injection-damping ring system used to inject into the PEP-II B-Factory can be used for this purpose, without any modification to the linear accelerator except for a sequence of 4 bending magnets to compress the electron bunch. With a charge of 3.4 nC per bunch accelerated to 28 GeV and a 10 m long undulator it is quite feasible to generate pulses of x-rays of 8.3 kV energy (in a spectrum extending to over 1 MeV), 80 fsec long (full-width-half-maximum), with a peak brightness of the order of 10{sup 25} photons/(sec x mm{sup 2} x mrad{sup 2} x 0.1% bandwidth), and 10{sup 8} photons per pulse in a 0.1% bandwidth. This facility could be built and operated ahead of the LCLS schedule and would provide both a powerful tool for research in its own right, as well as a way to conduct critical accelerator and x-ray optics R and D for the LCLS.
