Abstract :
A study, is made of the coherent beam-beam interaction in a collider with two rings of equal circumference for the counter-rotating beams, and in particular the case of DA Phi NE. There may be one or two active interaction points. The rings may have errors on the phase advances, etc. The bunch population may vary from bunch to bunch. It is shown that DA Phi NE can use the two interaction points at the same time, although care should be taken in the choice of these tunes, because of the existence of a complicated resonance structure in the tune diagram.<>
