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 the most 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 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 the corrugation in a mm-scale dielectric capillary and can be emitted through the outer dielectric boundary not covered by the reflector.
