| Research Abstract |
Effect of the noise from the bunch feedback system has been studied using KEKB collider. Degradation of luminosity and vertical beam size was measured quantitatively with the artificially injected noise. The results have been compared with the beam-beam simulation and have shown good agreements. Low noise feedback detector with good bunch isolation has also developed and tested using DAFNE collider. No degradation of luminosity with the feedback system was shown.
