Title: Transverse Damper Using Diodes for Slip Stacking in the Fermilab Recycler

Abstract

During slip stacking in the Recycler, up to six batches of 84 bunches each are slipped by each other to and then captured to double the intensity of the the extracted beam. For nominal chromaticity settings, a bunch by bunch transverse damper system is needed to maintain beam stability but this system is blind to the bunches as they are slipping. The initial solution was to drastically raise the chromaticity to keep the beam stable. A new frequency based damper using diode detectors was developed to provide damping during slip stacking and allow the chromaticity to be reduced to nominal settings.
