Improvement in RF Curves for Booster Running at High Intensities

Abstract

A feed-forward ramp can be implemented in Booster to compensate the beam energy loss at different beam intensities for the purpose of minimizing the radial error signal. This can be done only when we have a good understanding about the dependence between the beam energy loss per turn and the beam intensity experimentally. Besides, based upon this understanding we can predict the required accelerating voltage at the transition crossing for different beam intensities, which can be extremely helpful for Booster running at higher beam intensities than ever before.
