Free Electron Lasers and E-Beam Radiation Sources

Avi Gover, Professor of Engineering, Physical Electronics Department, Tel Aviv University

The physical principles and the state of the art of Free Electron Lasers and electron beam radiation sources will be reviewed. These devices can operate in the entire frequency regime, from microwaves to X-rays at very high intensities (MWatts range). At long wavelengths (THz regime), relatively compact sources of coherent radiation can be developed, based on stimulated and superradiant emission schemes. Varieties of these radiation sources are predicted to have important applications in scientific research (spectroscopy, holographic imaging of single bio-molecule), defense (anti-terrorist warfare, directed energy weapon) and industry (material and photochemical processing).
