“…Among various advanced accelerator concepts, the DL accelerator can be traced back to the early 1950's (Flesher 1951) and is a potential candidate for future high gradient particle acceleration. Although there are two main types of DL accelerators, one based on rectangular waveguides (Zhang 1997) and one based on circular waveguides (Zou 2000), in this thesis we concentrate on the latter.…”

“…The use of uniform dielectric-lined circular waveguides as accelerating structures has been discussed in many previous studies [3,4]. One distinct advantage is that the axial accelerating electric field is the maximum field in this class of structure.…”

One disadvantage of conventional iris-loaded accelerating structures is the high ratio of the peak surface electric field to the peak axial electric field useful for accelerating a beam. Typically this ratio E s /E a ≥ 2. The high surface electric field relative to the accelerating gradient may prove to be a limitation for realizing technologies for very high gradient accelerators. In this paper, we present a scheme that uses a hybrid dielectric and iris loaded periodic structure to reduce E s /E a to near unity, while the shunt impedance per unit length r and the quality factor Q compare favorably with conventional metallic structures. The analysis based on MAFIA simulations of such structures shows that we can lower the peak surface electric field close to the accelerating gradient while maintaining high acceleration efficiency as measured by r/Q. Numerical examples of X-band hybrid accelerating structures are given.

“…The concept of using dielectric loaded structure as acceleration structure has been around for many years [1], and in particular there have been a number of proposals to use dielectric loaded structures as collinear wakefield accelerators [2,3]. Recently, there have also been proposals to also use dielectric structures as power extraction devices for high frequency rf generation [4].…”

Abstract. We reporton the experimental results of the dielectric baaed two beam accelerator (step-up transformer). By using a single high charge beam, we have generated and extracted a high power RF pulse from a 7.8 GHz primary dieketric structure and then subsequently transferred to a seeond accelerating structure with higher dieketric constant and smaller transverse dimensions. We have measvred the energy change of a seeond (witness) beam passing through the acceleration stage. The measured gradient is >4 times the deeekration gradient. The detailed experiment of set-up and results of the measurements are dimmed. Future plans for the development of a 100 MeV demonstration accelerator based on this technique is presented.
