Investigations into X-band dielectric assist accelerating structures for future linear accelerators

Dielectric assist accelerating (DAA) structures are being studied as an alternative to conventional disk-loaded copper structures. This article investigates numerically an efficient $X$ -band DAA structure operating in a higher order mode of TM02- $\pi $ . This accelerating structure consists of dielectric disks with irises arranged periodically in a metallic enclosure. Through optimizations, the...
