APD signals from the 100 fs pulses (upper) at 640 eV and the background signals (middle) for the old BESSY storage ring optic (blue) and the so-called top-up optic (black) where the horizontal β-function was reduced to ∼10 m in the high-β straight sections; bump = −0.75 mrad, shift = 28 mm, sequenced mode at 6 kHz. The two lowest curves represent the laser-OFF case (picosecond-leftover from core beam) and the curves in the middle arise from the `halo' background, even lower in the top-up case.
