Description
In the context of the ongoing SOLEIL II upgrade, a measurement campaign was conducted to characterise and understand the behaviour of single- and coupled-bunch instabilities, and the performance of the transverse bunch-by-bunch feedback system at the present SOLEIL storage ring. This paper presents the key results of beam current thresholds measurements; growth-damp measurements with resistive feedback, drive-damp measurements with resistive feedback, tune shift measurements with reactive type of feedback. The results constitute a snapshot of instabilities and bunch-by-bunch feedback performance at SOLEIL. Our results guide in designing the bunch-by-bunch feedback system for SOLEIL II.
