Abstract:
A barrier bucket with small separation between the rf barriers (relative to the barrier widths) or even zero separation has its synchrotron tune decreasing rather slowly towards the boundary of the bucket. As a result, large area at the bucket edges can become unstable under the modulation of rf voltage and/or rf phase. Application in terms of bunch-distribution distortion and particle loss is made to those barrier buckets used in the process of momentum mining
at the Fermilab Recycler Ring.
