Abstract :
Use of grooved vacuum chambers have been suggested as a way to limit electron cloud accumulation in the ILC- DR. We report on simulations carried out using an augmented version of POSINST, accounting for e-cloud dynamics in the presence of grooves, and make contact with previous estimates of an effective secondary electron yield for grooved surfaces.
