Head tail instability observation and studies at the proton synchrotron booster

Since many years the Proton Synchrotron Booster (PSB) high intensity beams have shown head tail instabilities in all of the four rings at around 100 ms after the injection. In this paper we present the latest observations together with the evaluation of the instability rise time and its dependence o...

description Since many years the Proton Synchrotron Booster (PSB) high intensity beams have shown head tail instabilities in all of the four rings at around 100 ms after the injection. In this paper we present the latest observations together with the evaluation of the instability rise time and its dependence on the bunch intensity. The acquired head tail modes and the growth rates are compared with HEADTAIL numerical simulations, which together with the Sacherer theory points at the resistive wall impedance as a possible source of the instability.
