Description

Intra-train bunch charge at FLASH shows an RMS of approx. 2 pC at 0.4 nC, with periodic oscillation that originates from within an injection laser cavity. Noticeable adverse effects on the final SASE were reported recently. The implementation of a slow and fast intra-train charge feedback is discussed. The measurement results show sub-pC charge flatness with the feed-back activated.
