Novel superconducting rf structure for ampere-class beam current for multi-GeV energy recovery linacs
Future ampere-class energy recovery linacs (ERLs) based on superconducting technology demand efficient damping of the higher-order modes in the superconducting radio-frequency (SRF) accelerating structures to achieve stable beam operation in multipass, multibeam ERLs. We propose a new and novel SRF...

| description | Future ampere-class energy recovery linacs (ERLs) based on superconducting technology demand efficient damping of the higher-order modes in the superconducting radio-frequency (SRF) accelerating structures to achieve stable beam operation in multipass, multibeam ERLs. We propose a new and novel SRF structure that is extremely efficient in damping the higher-order modes of SRF structures for ERLs. Initial simulation results indicate extremely good and efficient damping of the dipole and the quadrupole modes that determine the beam breakup threshold of the superconducting structures. The proposed new structure has the added benefit of having simpler fabrication steps with potential fabrication cost savings. |
