Title: Niobium-coated copper cavities for the eRHIC crabbing system

Abstract

Crabbing of hadron bunches in particle colliders requires high kick voltages in the order of MV. The crabbing system of the High Luminosity Large Hadron Collider (HL-LHC) will be using Double-Quarter Wave (DQW) and Radio-Frequency Dipole (RFD) cavities, both compact deflecting cavity designs fabricated from bulk Nb sheets. In the same fashion, the baseline crabbing system for the electron Relativistic Heavy Ion Collider (eRHIC) will consist of a series of DQWcavities. Encouraging cryogenic RF performances of a Nb/Cu Quarter-Wave Resonator (QWR) and the proposal of a niobium-coated copper (Nb/Cu) Wide- OpenedWaveguide (WOW) cavity for deflecting purposes stimulated the necessity to review the possibilities of Nb/Cu cavities for the future crabbing system of eRHIC. This note will study the feasibility of usingWOW cavities for the eRHIC crabbing system and will compare the expected performances of DQW and WOW cavities based on the latest cryogenic RF results.
