  • Basic principle of SASE High peak brilliance (exceeding storage rings by several order of magnitudes). High degree of transverse coherence close to saturationSpontaneous emissionSaturationExponential Growth Jean-Paul Carneiro, FNAL, 16-Sept-04 4 DESY superconducting SASE FELs

  • Successful demonstration of FEL saturation for sub-micrometers wavelengths :

    LEUTL : 385 nm (Sept. 2000)

    TTF1 : shortest wavelengths obtained at TTF1 at DESY (1st saturation @ 98 nm in Sept. 2001) saturation obtained from 80 nm to 120 nm FEL saturation for sub-micrometer wavelengths Jean-Paul Carneiro, FNAL, 16-Sept-04 5 DESY superconducting SASE FELs

  • Tesla Test Facility, Phase 1 / Rsum TTF phase 1 has been concluded successfully

    Saturation observed in the wavelength of 80-120 nm

    Peak brilliance as expected

    ~1.5 GW of peak power in flashes of 30 -100 fs

    Good agreement between observations and simulation codes (ASTRA / ELEGANT / FAST)
