Description
The accelerating gradient in conventional radio-frequency accelerators is limited to 100 MeV/m. A promising solution is to use wakefield effects either in dielectrics or plasma, where breakdown limit is higher.
Cherenkov radiation (CR) is considered to be the main mechanism in dielectric wakefield acceleration (DWA). Our preliminary study with corrugated capillaries show some modification to the CR-generated wakefields [K.V. Lekomtsev et al., Phys. Rev. AB 21, 051301 (2018)], but the possibility of using Smith-Purcell radiation (SPR) in DWA is still under consideration. Here we propose to apply SPR in DWA instead of CR. Theoretical results are compared with computer simulation.
