Description
- Keywords: Longitudinal instabilities, past and future RF improvements, beam quality, bunch rotation
- Questions to be answered:
- What is the parameter reach in terms of intensity/longitudinal emittance? What was achieved in 2018 and what is expected from simulations with the further LS2 RF improvements?
- What is the contribution of each of the upgrades (coupled-bunch, 1-turn delay, multi-harmonic feedbacks)?
- Which impedance sources mainly excite the observed instabilities?
- Are there any new ideas to further improve the longitudinal beam quality, e.g. bunch shape after rotation, to better suit the SPS?
- What are the observed and expected bunch-by-bunch parameter variations (2018 and post-LIU)?
