    "abstract": "The e-e- running mode is one of the interesting physics options at the\nInternational Linear Collider (ILC). The luminosity for e-e- collisions is\nreduced by the beam-beam effects. The resulting beamstrahlung energy loss and\nbeam-beam deflection angles as function of the vertical transverse offset are\ndifferent compared to the e+e- collisions. In this paper, the dependence of\nthese observables with the offset for different beam sizes has been analyzed to\noptimize performances for the e-e- mode, taking into account the requirements\nof the beam-beam deflection based intra-train feedback system. A first study of\nthe implications for the final focus and extraction line optics is also\npresented for the cases of the 20 mrad and 2 mrad ILC base line crossing angle\ngeometries.",
