✦ Synopsis
We determine action dependent damping coefficients for electron coolers with cylindrical and hollow beams and action dependent diffusion coefficients from the interaction with a target and a simple model of intrabeam scattering. We use these coefficients to numerically solve the time-dependent Fokker-Planck equation and present simulations of the transient cooling down. An efficient integrator makes it possible to simulate long times (hours) very efficiently and quickly. Moreover we determine a maximum acceptable limit of the cooling time to provide stable operation.
