Presents the design of a fast-tuning system based on nickel-zinc ferrite for a 24.6 MHz accelerating cavity, developed to compensate for frequency shifts during transition crossing in a hadron storage ring. Covers ferrite material selection, tuner mechanical design, and expected RF performance.
Describes the engineering approach used to convert existing 28 MHz RF cavities to operate at 24.6 MHz for use in the EIC Hadron Storage Ring, including modifications to cavity geometry and tuning range, along with RF performance validation.
Reports on the use of evolutionary optimization algorithms to refine the geometry of a 591 MHz single-cell superconducting RF cavity, aiming to improve RF performance parameters such as peak surface fields and shunt impedance.
Presents simulation studies of trapped higher-order modes and wakefield effects associated with bellows components in 197 MHz superconducting crab cavities, evaluating their impact on beam quality and cavity performance.
