Abstract :
Stability analysis is presented for an antiproton beam interacting with an electron beam of an “electron lens” proposed as a beam-beam tune shift compensator. Coherent antiproton-electron interaction causes coupling of the antiproton synchrobetatron modes which may lead to a transverse mode coupling instability (TMCI). Analytical studies and numerical simulations of this effect are presented
