Wakefield and impedance studies of a liner using MAFIA

Technical Report ·
OSTI ID:10169698
The liner is a perforated beam tube that is coaxial with an outer bore tube. The 3D code MAFIA (version 3.1) is used to study the wakefields, impedances, and resonances of this structure. The short-range wakes and low-frequency (below the cutoff) impedances are in agreement with the theoretical model. The long-range wakes and high-frequency resonances are associated with the distribution of the holes (or slots). The dependence of the impedance on the size, shape, and pattern of the holes (or slots) is studied. The impact of the liner impedance on the Superconducting Super Collider impedance budget is discussed.
