An additional 500 Mc s −1 cavity, fifth harmonics of the main cavity, was installed on the Super-ACO storage ring in order to shorten the bunch length. This cavity was introduced to obtain shorter wavelengths in the UV for the FEL and shorter flash

New outlooks on bunched beam instabilities in particle accelerators. A proposal for a simple method to release a potential self-consistent high quality beam

Autor: M. Bergher

Publikováno v: Proceedings of International Conference on Particle Accelerators.

Several hypotheses have been proposed to explain bunched beam instabilities under increasing intensity. In fact, the cause of these instabilities can be used to generate a very high quality beam. Total coherent synchrotron radiation brings the bunche

Supercooling of bunched beams by coherent synchrotron radiation

Autor: M. Bergher

Publikováno v: Proceedings Particle Accelerator Conference.

Longitudinal and transverse dimensions of bunched beams may be cooled by coherent synchrotron radiation in storage rings. The cooling starts if the bunches are short enough. Coherent synchrotron radiation with wavelengths of the order of the length o

The CLIO (Collaboration pour un laser infra-rouge a Orsay) project involves an FEL and a dedicated 50 MeV rf linac being built at Orsay. We have completed its 4 MeV injector. It consists of a pulsed thermionic gun, a 500 MHz subharmonic prebuncher an
