|
|
-
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;

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.
