Title: SHORT-RANGE WAKEFIELD CALCULATIONS FOR THE ION CLEARING ELECTRODES IN THE CORNELL ENERGY RECOVERY LINAC

Abstract: The presence of trapped ions in the Cornell Energy Recovery Linac (ERL) can lead to beam halo, particle loss, optical errors, or transverse and longitudinal instabilities. DC clearing electrodes that create a sufficient voltage to draw ions out of the beam potential are considered to be the most easily applicable measure to cure these effects. However, due to the short length of electron bunches in the ERL running modes, the power dissipated by the clearing electrodes can significantly damage these. I have calculated the short-range wakefields of different types of clearing electrodes and concluded that a tapered electrode design can be used.
