Picosecond-long x-ray pulses of moderate intensity and high repetition rate are highly sought after by the light sources community, e.g. for time-resolved investigations matter in linear response regime. We investigate upgrade a diffraction-limited storage ring source to short X-ray pulse scheme. Short emitted electron bunches magnetically compressed injection chain, with no impact on simultaneous standard emission from long bunches. The ultimate performance, limits operational aspects scheme discussed terms soft undulator emission.
