Phys. Rev. Lett. 95, 114801 (2005) [4 pages]Whispering-Gallery-Mode Resonances: A New Way to Accelerate Charged ParticlesSee Also: Erratum Received 2 June 2005; published 8 September 2005 Looking for future high energy accelerators we point at a very strong interaction between relativistic electrons and powerful electromagnetic fields existing in the vicinity of a dielectric cylinder in conditions of resonantly excited whispering gallery modes (WGM). A particular example of the WGM resonance, corresponding to angular index n=22, shows that the accelerating fields are almost 100 times stronger than these in the incident wave. That yields an acceleration rate of about 5 GeV/m with the incident microwave radiation beam of the wavelength λ=1 cm and a moderately high intensity of P=1 MW/cm2. © 2005 The American Physical Society URL:
