The impact of the resistive-wall impedance on the ILSF storage ring

The resistive contribution of the vacuum chamber represents a significant source of the collective effects and should be analysed in several aspects. Due to the NEG-coated redesigned ILSF vacuum chamber, the resistive-wall effects were carefully studied. The measurement setup of the RW test was simulated and compared with the analytical equations. Finally, the longitudinal threshold was presented here to estimate the RW effects on the single bunch instability.
