Abstract

At SOLEIL, the time resolved community benefits from a single bunch operation few weeks a year. Meanwhile most of the multi-bunch filling pattern based experiments are not possible due to the low photon flux. Following the pioneer work performed at ALS [1], a new operation mode is under study at SOLEIL where the storage ring is filled up with a special hybrid mode: 3/4 multi-bunch filling pattern and a single bunch with higher current in the last 1/4. The so-called pseudo single bunch-filling pattern is obtained if the closed orbit of the single bunch is not the same as the one of the other bunches. Preliminary results are presented where the existing fast kicker magnet time impulse response has been significantly reduced while its frequency was increased from 3 Hz up to 1 kHz. This magnet is used as an additional corrector magnet to change only the single bunch closed orbit. First experimental results observed at one interested beam-line are also discussed.
