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

Mina Akhyani

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. T ...
