Relativistic magnetized electron cooling is an essential technique for achieving the ion beam luminosity requirements of next-generation electron-ion collider facilities. Because the cooling system will have to operate in previously untested parameter regimes, accurate computation of magnetized dynamic friction is required at the design stage. For energies of interest to the proposed polarized electron-ion collider (EIC), the interaction time in the cooling section becomes short compared to the plasma period. We present the results of a new semi-analytic treatment of momentum transfer from an ion to a distribution of magnetized electrons, and discuss its application to calculation of dynamic friction in the parameter regime relevant to the EIC cooling system design.
