Long-range beam-beam mitigation for round optics
/ Fartoukh, Stephane (CERN) ; Kostoglou, Sofia (CERN)
When colliding high intensity bunch trains at low beta*, a sufficiently large crossing angle needs to be imposed at the interaction point (IP) in order to separate the two beams before and after the collision, and mitigate the so-called long-range beam-beam (BBLR) effect, which otherwise can be very detrimental to the beam lifetime.
