Observation of transverse quadrupolar tune shifts in the Photon Factory storage ring

Observation of transverse quadrupolar tune shifts in the Photon Factory storage ring

The frequencies (tunes) of transverse quadrupolar oscillations were measured in the 2.5-GeV Photon Factory storage ring at the High Energy Accelerator Research Organization (KEK). As a result, remarkable shifts in the quadrupolar frequencies with the bunch current were found; they were both positive...
