Abstract :
In the present paper we repeat the exercise of an earlier paper but with a new wakefield. The impedance which used to be inductive has become resistive, leading to different phenomena. In a recent paper the instability in a purely resistive ring is analyzed using a Vlasov equation approach. It is demonstrated that such an instability is a weak instability, with a growth rate proportional to intensity squared, and one that can be described as the coupling of two quadrupole modes with different radial mode numbers. We will compare our results with this paper
