MEASUREMENT OF TRANSVERSE BUNCH SIZE BLOW-UP DUE TO THE ELECTRON CLOUD INSTABILITY AT PEP-II
- SLAC
The electron cloud instability at PEP-II is responsible for enlargement of the transverse bunch size for positron bunches at high current. Presented in this paper are the measurements of transverse beam blow-up taken by a two nanosecond-gated camera. The measurements point out that a current-ramp, mini-gaps between trains, and arc solenoid windings help reduce the positron bunch size blow-up due to the electron cloud instability.
