Abstract
The quadrupolar tune shift is a measure of the quadrupole component of wakefields in storage rings. By measuring both dipolar and quadrupolar tune shifts, we can estimate dipolar and quadrupolar kick factors independently. We carried out these measurements before and after the reconstruction of the photon factory storage ring at KEK. The results showed remarkable changes in the quadrupolar tune shifts in both horizontal and vertical planes, together with slight changes in the dipolar tune shifts.
