The future colliders pushing the energy and luminosity frontiers and particle accelerators with multi-experimental stations have expanded the need of deflecting/crabbing cavities. The current applications in need of such cavities operate at low frequencies and have also specifications with strict dimensional constraints, high operating transverse gradients, and tight impedance budgets. At low operating frequencies the use of standard cavities operating in TM110-like modes has been very challenging. A new type of superconducting deflecting/crabbing structure has been designed that has a wide range of applications. The new rf-dipole cavity operates in a TE11-like mode where several cavities have been fabricated, and tested. The rf performance shows that these structures are capable of operating at high transverse gradients and will be a very attractive deflecting/crabbing cavity for many current applications. At present, a 400 MHz rf-dipole crabbing cavity system is under development to be tested at SPS at LHC as part of the LHC High Luminosity Upgrade. PB - JACoW CP - Geneva, Switzerland ER -
