Description
Transverse emittance growth was observed during the long injection plateau for high-intensity multi-bunch LHC-type beams in the CERN SPS, showing a clear dependence on the working point. Transverse tunes were increased to reduce emittance growth driven by integer resonances; however, a residual increase in emittance persists. To characterize this behavior and investigate its possible causes, transverse profile measurements were performed with the SPS wire scanners at several points along the injection plateau. These measurements are used to quantify the evolution of the transverse emittances and to assess the presence and possible generation of overpopulated tails.
