Session 6: Diagnostics for instability observations
- Tatiana Pieloni (EPF Lausanne)
A horizontal head-tail instability has been observed in the CERN Proton Synchrotron Booster (PSB) since the ‘70s. Beam-based measurements of losses versus the horizontal working point reveal a dependence of the instability on the horizontal tune. Macro-particle simulations and the Sacherer formalism suggest that the unmatched kicker termination is responsible for the observed beam losses and...
