Novel THz radiation source based on compact linear accelerator.

Marie Curie Research Fellow: Konstantin Lekomtsev

Research objectives:

  • to investigate Cherenkov and Smith - Purcell mechanisms for THz radiation generation using EM simulation tools and propose an efficient target configuration and observation geometry;

  • to build a radiation source that provides high peak power levels and based on a compact linear accelerator technology with a fs-duration beam;

  • to evaluate possible applications of the investigated radiation mechanisms for beam position and bunch length diagnostics;

  • to provide knowledge exchange between partner organisations and other interested parties via seminars, satellite and progress meetings, conferences and workshops;

  • to improve public awareness about the ongoing research via outreach activities;

  • to develop project management skills.

Generation of THz radiation from dielectric mm-scale capillaries with reflectors.

Demonstrated that coherent Smith Purcell Radiation, with intensity comparable to that of coherent Transition Radiation, can be generated as a result of introducing a corrugation in a mm-scale dielectric capillary and can be emitted through an outer dielectric boundary not covered by a reflector.

Brief description of experiment

Drive-Witness acceleration scheme based on corrugated dielectric mm-scale capillary.

An experimental scheme based on a mm-scale corrugated capillary proposed as an accelerator/decelerator with an adjustable wakefield pattern, and was used to study beam dynamics at different transverse beam off-sets.
