Stimulated dielectric wake-field accelerator

Coherent multimoded dielectric wakefield accelerators

“…Another aspect of the work in reference [1] is the suggestion that driving a multimode structure with a train of periodically spaced bunches would allow stimulated theorem still holds, even though our numerical calculations agree with reference [1]. We also found the wakefield enhancement due to the use of multiple drive bunches simply scales with the total charge if one assumes all the beam parameters are the same for the individual bunches in the train.…”

Experimental demonstration of dielectric structure based two beam acceleration

“…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].…”

Creation of femtosecond sheet-like bunches for driving optical-scale dielectric slab accelerator structures

“…An attractive feature of a 2D planar dielectric structure was discovered in 1997 for a microwave-scale wake field accelerator [2]. It was shown that the structure can be designed so that many TM-like guided modes are excited by short charge bunches, and that the fundamental period *Research supported by the DoE, Division of High Energy Physics.…”

“…Optically-resonant structures can be precisely fabricated using microcircuit techniques. A specific accelerator concept that could benefit by using laser-wavelength scale structures is the dielectric wakefield accelerator [1,2], discussed here.…”
