Photoinjector accelerating system for sub-mm high-power pulse source
Generation of high-intensity sub-mm electromagnetic radiation can be performed by means of the scheme that implies generation of radiation by short monochromatic bunch of electrons which is traveling through dielectric or corrugated capillary. Short bunch of electrons can be obtained by using of a p...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Generation of high-intensity sub-mm electromagnetic radiation can be performed by means of the scheme that implies generation of radiation by short monochromatic bunch of electrons which is traveling through dielectric or corrugated capillary. Short bunch of electrons can be obtained by using of a photoinjector. R&D of accelerating systems of S-band photoinjector and analysis of electron bunch dynamics in this system are declared. The aim of the work is to find optimal model providing large value of efficiency and magnitude of accelerating field with low RF power. Different structure's types are considered to achieve this aim, such as 1.6 cell disk-loaded waveguide (DLW) and 3 cells and 2 half-cells of DLW. Structure based on 7 cells and 2 half-cells of DLW and travelling wave resonator (TWR) based system are analyzed to consider the possibility of increasing the electrical strength of the system and decreasing of requirements to RF power source. Results of electrodynamics characteristics analysis of accelerating structures resonant models and structures with power ports are presented. Electron bunch dynamics study results are also discussed. |
