  3. TTF2 LASER (ASTRA GENERATOR OUTPUTS, 2E5 p.) • Transverse distribution : uniform, r = 1.5 mm • Longitudinal distribution : uniform, L=20 ps with ~5 ps rise times • Thermal emittance : 55 keV From TELSA-FEL 97-01 (K. Floettmann) : Longitudinal distribution Transverse distribution Jean-Paul Carneiro FIRST OPERATION OF THE TTF2 INJECTOR WITH BEAM

  4. PHASE SCAN OF TESLA XFEL WITH ASTRA • TTF2 NOMINAL : 40 MV/m, 0.163 T, L = 20 ps + 3 ps rise time, r =1.5 mm (plot presented at the S2E Workshop, DESY ZEUTHEN, AUG-2002, http://www.desy.de/s2e) Jean-Paul Carneiro FIRST OPERATION OF THE TTF2 INJECTOR WITH BEAM
