Bunch Pattern by-3 in PEP-II

Creators

Description

After a long 4-month down time where additional RF was installed and heating problems addressed, the PEP-II B-factory should be capable to delivering about 1.5 times the currents. This can only be done by going to more bunches from a full by-4 pattern to either a partly filled by-3 or by-2 pattern. The by-2 pattern has parasitic crossings, so the by-3 pattern is the next candidate. Heating issues from the different higher order modes, especially in the longitudinal and transverse feedback structures are a concern. Effects from an electron cloud seem to be still visible in the by-3 and by-2 pattern
