100 bunch DA/spl Phi/NE operation

The DA/spl Phi/NE collider has been operating by filling 100 consecutive buckets out of the available 120 with a gap to avoid ion trapping in the electron beam. To reduce the effect of the parasitic crossings the crossing angle has been increased up to 29 mrad and the horizontal beta function at the interaction point lowered down to 1.7 m. Moreover both transverse and longitudinal feedbacks have been optimized for this more demanding mode of operation. Comparison between 100 and 50 bunches operation in 2002 runs is presented.
