TI - Performance Evaluation of the Intra-Bunch Feedback System at J-PARC Main Ring
J2 - Proc. of IBIC2014
AB - Intra-bunch feedback system in J-PARC (Japan Proton Accelerator Complex) Main Ring(MR) has been developed for suppression of head-tail motion and reduction of beam loss. This system consists of mainly BPM, signal processing circuit (iGp12), power amplifiers, and stripline kickers. These components were fabricated and installed in April of 2014. This system succeeded in suppressing the internal bunch motion caused by injection kicker error in the 3GeV constant-energy operation, and showed shorter damping time compared to the bunch by bunch feedback system, which is currently working in the normal operation. In this paper, we will report the performance of the system by comparison with simulations.
