RF Steering in the CEBAF CW Superconducting Linac

Conference ·
OSTI ID:954103

There exists a transverse gradient of the electric field parallel to the beam axis in the fundamental rf power coupler for the superconducting, five-cell cavity to be used in the CEBAF 0.5-4.0 GeV, cw, electron accelerator.This electric field gradient results in a transverse deflection of the electrons the magnitude of which varies during the passage of a microbunch, causing a dilution of the transverse emittance.This paper describes the estimate of the transverse deflection and the simulations performed to evaluate the magnitude of the emittance dilution caused by this deflection.The results of these simulations and the method used to reduce this effect are discussed.
