The impact of fill patterns on the fast ion instability in the ILC damping ring

    Abstract

    The ions produced via collisional ionization of the residual gas molecules in vacuumpipe with the circulating electron beam have deleterious effect on the beam properties andmay become a limiting factor for the machine's performance. For the electron damping ringof the International Linear Collider (ILC), the ion instability is noticeable due to theultra-low beam emittance with many bunches operation. In this paper, the different beamfill patterns are investigated and their effects on the fast ion instability are discussed.The simulations show that the mini train fill patterns can reduce the growth of the fastion instability significantly.
