Abstract

To reach high-peak powers and high efficiencies with a Free Electron Laser (FEL), the following components have been designed and will be described : i) a photo-injector using an RF gun cavity at 144 MHz to produce electron bunches, ii) a 433 MHz 3-cell cavity powered by a new 6 MW peak power and 200 μs pulse duration klystron, iii) a tapered hybrid wiggler using permanent magnets and pulsed coils for online fine tuning . By integrating these three main components (photo-injector, accelerating cavities, tapered wiggler coupled to an optical cavity), an experiment will be performed in the 20 μm range. Simulation codes have also been developed to follow electron bunches from the cathode down through the injector, the accelerator and the transport system. The physical and technical parameters of the wiggler have been optimized as well to maintain a strong interaction strength between electrons and photons.
