High Current Multibunch Operation at Da Ne
نویسنده
چکیده
At present the Frascati Φ-factory DAΦNE is operating in multibunch regime with stored currents in the range of 0.5-1 A in both e+ and erings. A longitudinal bunch-bybunch feedback system has been operating in each DAΦNE main ring since the beginning of the machine commissioning. The transverse bunch-by-bunch feedback system working in the vertical plane has been implemented last year in both rings. This paper describes the performance of the feedback systems and reports the instability observations and the rise-time measurements. The present current limitations and the plans aimed at further current increase are also discussed.

Transverse Multibunch Instabilities for Non-Rigid Bunches
In this paper, we present a method for computing growth rates and frequency shifts of a beam containing multiple non-rigid bunches. With this approach, we calculate non-rigid multibunch effects which can impact phenomena which are traditionally treated as single-bunch effects, such as the transverse mode-coupling instability. This approach is important for high current storage rings such as PEP...
متن کاملDiagnostics and Analysis of Instabilities with the Digital Transverse Multibunch Feedback at Elettra
The commissioning of the digital transverse feedback system at ELETTRA provides a valuable tool for the diagnosis and the study of transverse instabilities. The possibility of visualizing and analyzing the details of the time evolution enables the extraction of information regarding unstable and stable modes, such as growth and damping rates and their dependence on the harmonic sextupole. In th...
متن کاملExperimental investigation of multibunch, multipass beam breakup in the Jefferson Laboratory Free Electron Laser Upgrade Driver
In recirculating accelerators, and, in particular, energy-recovery linacs, the maximum current can be limited by multipass, multibunch beam breakup (BBU), which occurs when the electron beam interacts with the higher-order modes (HOMs) of an accelerating cavity on the accelerating pass and again on the energy recovering pass. This effect is of particular concern in the design of modern high ave...
متن کاملTransverse Multibunch Modes for Non - Rigid Bunches , Including Mode Coupling ∗
A method for computing transverse multibunch growth rates and frequency shifts in rings, which has been described previously [1, 2], is applied to the PEP-II B factory. The method allows multibunch modes with different internal-bunch oscillation modes to couple to one another, similar to single-bunch mode coupling. Including coupling between the multibunch modes gives effects similar to those s...
