Abstract Generation of two sub-femtosecond x-ray pulses with different and adjustable photon energies using a single electron bunch was considered in for x-ray pump and x-ray probe experiments with a variable time delay between the first and the second x-ray pulses. A combination of the echo-enabled harmonic generation (EEHG) technique and the current enhanced self-amplified spontaneous emission (ESASE) technique was employed in order to produce two spikes in the electron peak current containing high-frequency peak current modulations (microbunching) inside them. This microbunching was essential for coherent radiation in the two short undulators located downstream.
