Bunch-by-bunch Feedback Systems for Kekb Rings
نویسندگان
چکیده
Bunch-by-bunch feedback systems for curing coupled-bunch instabilities in the KEKB rings have been constructed. Even at a very early stage of the commissioning of the rings, strong transverse instabilities occurred in both rings which limited maximum storable currents. Stabilization of the beams with transverse feedback systems has been successful so far, enabling us to accumulate greater beam currents and to reduce part of the background in the interaction region. A preliminary report of transient-domain analysis of the instabilities using bunch oscillation memories is also given.

Beam Diagnostics Using Bunch-by-bunch Feedback Systems in the Kekb Rings
Transverse bunch-by-bunch feedback systems for damping coupled-bunch instabilities in the KEKB rings have been working well since the early stages of the commissioning of the rings. Beam diagnostic systems that are the part of the bunch feedback systems, such as bunch current monitors, betatron-tune measurements systems, and bunch oscillation recorders, have been playing important roles in the ...
متن کاملBunch by Bunch Feedback Systems for the Kekb Rings
Transverse bunch-by-bunch feedback systems for damping coupled-bunch instabilities in the KEKB rings have been working since the early stage of the commissioning of the rings. Stabilization of the beams with the system have been successful, permitting tests of higher beam currents and various filling patterns. The performance of these systems has been demonstrated under the normal physics run p...
متن کاملCommissioning of Kekb Bunch Feedback Systems
Commissioning of KEKB started at the end of the last year. In the early stages of the commissioning, we observed transverse instabilities in both rings and started tuning of the bunch feedback systems. Even though the tuning is now at the initial stage, the feedback systems are contributing to an increase of the maximum storable currents in the KEKB rings. Feedback-related systems, tune meters ...
متن کاملRecent Progress in the Development of the Bunch Feedback Systems for Kekb
In KEKB, which is a B-factory project at KEK, the bunch spacing is very short, only 2 ns, and the number of the bunches comes up to about 5000 per ring. In order to cure the instabilities due to the high beam current, we will use bunch feedback systems in KEKB rings. Recently we developed the new position detection system and made a prototype of the signal process system for the feedback system...
متن کاملFeedback experiments in TRISTAN-AR and the bunch by bunch feedback systems for KEKB
Beam tests of the KEKB bunch by bunch feedback system prototypes have been performed in the TRISTAN-AR in both longitudinal and transverse planes. A two-tap FIR filter system, consisting of hardware logic’s, realized the function of the phase shift by 90 degrees, the suppression of the static component and the delay of up to a few tens of turns in longitudinal plane with 508 MHz of system clock...
