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 in order to obtain reliable estimates of the cooling time. At energies of interest to the EIC cooling system design, the beam-frame interaction time in the cooler becomes short compared to the plasma period, and some assumptions applicable to the physics of cooling at lower energies become invalid in this high-energy setting. We present and discuss the results of first-principles modeling the magnetized dynamic friction force in the strong-field, short-interaction-time regime, as well as a parametric longitudinal friction force model that we developed starting with a reduced ion-electron interaction potential. The model parameters are related in a simple way to the interaction time and the ion charge. We compare our simulation results to the predictions of previously developed theoretical models.
