摘要：

Feedback systems installed for control of coupled-bunch longitudinal instabilities in PEP-H collider have been designed to process bunch data at one half of the ring RF frequency. As a result these systems are ideally suited for controlling ring fills where only even or only odd RF buckets are populated (even bunch spacings). However in the operation of PEP-II per bunch charge considerations require fill patterns that alternately populate even and odd buckets. In this note we present a technique that allows to use existing hardware to provide feedback control of all bunches in such fills.
