| Abstract | We study an improved SASE (iSASE) scheme to generate narrow bandwidth X- ray FEL pulses by introducing repeating delays of the electron beam respect to the radiation field, thus mixing the spikes phase and amplitude, increasing the cooperation length and generating a bandwidth much smaller than in the SASE case. The improved longitudinal coherence is used, in combination with a tapered undulator, to increase the efficiency of energy transfer to the radiation and generate ultra-high peak power. We report results of theoretical and simulations studies for a hard X-ray iSASE FEL at 0.15 nm, using an LCLS-II undulator to generate X-ray pulses with peak power between 0.1 and 1 TW. The analysis is carried out using a time dependent 1-dimensional model and with GENESIS numerical simulation including 3dimensional effects. |
