A unique X-ray source, of exceptional brightness and with pulse widths as low as 30 fs rms, has been proposed at the Stanford Linear Accelerator Center. Named the Sub-Picosecond Photon Source (SPPS), the facility takes 30 Gev bunches from the linac and compresses them in three stages to achieve peak currents of 30 kA in the Final Focus Test Beam (FFTB) beamline. The existing FFTB can accommodate an undulator of up to 10 m in length which will deliver ~108 1.5 A photons per pulse in a 0.1% bandwidth with a peak brightness of ~1025 photons/sec/mm2/mrad2/0.1% BW, in a pulse width of ~80 fs FWHM. The short electron bunches are also ideal for plasma and wakefield studies as well as providing abundant R&D possibilities for verifying short bunch behavior in the future Linac Coherent Light Source (LCLS).
