SLIDE 1 Coherent beambeam e#ects study. ... He has shown that a finite length (in other words equal to # # ) of colliding bunches can lead to the coupling of synchrobetatron modes in the beambeam system, and thus a headtail type instability of colliding bunches may arise. ... These modes have been observed in di#erent machines. ... SLIDE 5 Figure shows the dependence of the measured and calculated synchrobetatron mode tunes on the beam current for equal electron and positron bunch intensities. ...
