BEAM-BASED FEEDBACKS FOR THE FERMI@Elettra FREE ELECTRON LASER*
FERMI@Elettra is a new 4-generation light source based on a single pass Free Electron Laser (FEL) providing high peak-power photon pulses. It consists of a 1.5-GeV normal-conducting linac working at 50 Hz repetition rate and two chains of undulators where the photon beams are produced with a seeded laser multistage mechanism. A number of control loops, some of them working on a shot-by-shot bas...
متن کاملExtreme ultraviolet multilayer for the FERMI@Elettra free electron laser beam transport system.
In this work we present the design of a Pd/B₄C multilayer structure optimized for high reflectance at 6.67 nm. The structure has been deposited and also characterized along one year in order to investigate its temporal stability. This coating has been developed for the beam transport system of FERMI@Elettra Free Electron Laser: the use of an additional aperiodic capping layer on top of the stru...
متن کاملSingle-pass High-gain Free Electron Laser Electron Beam Diagnostics
Consensus reached in the last few years that fourth generation light source will most likely be a X-ray or a UV coherent source based on single-pass high-gain free electron laser (FEL), such as Self Amplified Spontaneous Emission (SASE), or seeded high-gain harmonic -generation (HGHG) free electron lasers. High -gain (> 10) required for single-pass FEL puts great constrain on the quality of ele...
متن کاملTiming methodologies and studies at the FERMI free-electron laser.
Time-resolved investigations have begun a new era of chemistry and physics, enabling the monitoring in real time of the dynamics of chemical reactions and matter. Induced transient optical absorption is a basic ultrafast electronic effect, originated by a partial depletion of the valence band, that can be triggered by exposing insulators and semiconductors to sub-picosecond extreme-ultraviolet ...
متن کاملSimulation of Laser - Electron Beam Interaction in the Optical Klystron of a Free Electron Laser
The particle optics code GPT [1] has been applied to study the single pass electron beam interaction with an external laser field in the undulator system of a free electron laser. In particular, this code has been used to simulate the laser electron beam interaction in an optical klystron. Micro-bunching as a result of the interaction of the electron bunch with an electromagnetic pulse is prese...
