Abstract

The transport properties of the CEBAF 5-cell cavity are studied. The 3-D cavity fields are calculated by use of the 3-D program MAFIA and are incorporated in a modified PARMELA. Numerical simulation results show that the cavity has finite dipole, quadrupole and skew quadrupole field components, which are due to the asymmetric field in the fundamental and the higher-order-mode couplers. The azimuthal focusing of the cavity disappears for high energy particles as ½_γ. The dependence on the initial energy and cavity phase is given. The cavity-steering effects were measured on the CEBAF 45 MeV injector and are in good agreement with the numerical simulation
