Preprint PFC/JA-81-19 TWO-STREAM, FREE ELECTRON LASERS
نویسندگان
چکیده
Two parallel, relativistic electron streams with different velocities support unstable, exponentially growing space-charge waves, and efficient electron bunching may be achieved in the submillimeter wavelength range. Injection of the prebunched streams into a static, periodic (wiggler) magnetic field enhances the intensity of the parametrically excited, back-scattered electromagnetic wave. Calculations are presented of wave enhancement and wave growth in the Raman regime, for the case of two cold, perfectly intermingled prebunched streams. This work was supported in part by the National Science Foundation under Grant ENG79-07047 and in part by the U.S. Air Force Office of Scientific Research under Grant AFOSR-77-3143.

PFC / JA - 89 - 48 A Planar Electromagnet Microwiggler for Free Electron Lasers
We have designed and tested an electromagnet planar microwiggler for use in free-electron lasers (FELs), constructed of current conductors wound on ferromagnetic cores. A prototype with a period of 1 cm and gap of 0.5 cm produced a peak field on axis in excess of 4.6 kG, with a linear B/H characteristic to about 3.2 kG. The field of each half-period of the wiggler is independently tuneable by a...
متن کاملPFC/JA-92-26 Growth and Saturation of Stimulated Beam Modulation in a Two-Stream Relativistic Klystron Amplifier
A novel two-stream relativistic klystron amplifier (RKA) is presented in which the amplification of stimulated beam modulation is achieved via the unstable two-stream interaction rather than the use of passive cavities. After a calculation of the limiting current, the amplification and saturation of the stimulated beam modulation are analyzed using a cold-fluid model and particle-in-cell simula...
