abstract = {{Because the efficacy of conventional electron cooling falls off rapidly with energy, reaching the cooling times at collision energy targeted by the Electron-Ion Collider (EIC) design can be challenging. A possible solution is offered by cooling schemes that are based on fundamentally different techniques such as microbunched electron cooling (MBEC). Regular PIC simulations of MBEC in the parameter regime of the EIC cooling system would require a prohibitively large number of particles to resolve the evolution of the ion-imprinted phase space density modulation. We explored a solution to this problem by developing and implementing in the code Warp an approach based on two perturbative techniques, the beam-frame delta-f method and a variant of the distribution difference (DD) technique. To model the dynamics of the ion-seeded modulation in the MBEC chicanes, we developed an approach that combines the DD and quiet start techniques with analysis of correlations between the divergence of DD trajectories and their location within the e-beam. We have also prototyped in Warp the computation of the time-dependent 3D wakefield in the MBEC kicker.}},
