چکیده
Last year an intense electron beam produced by an induction accelerator was bunched using a Free Electron Laser and used to generate radio-frequency power by its passage through a resonant cavity. An improved version of this experiment has been carried out in the last few months. Our aims were mainly to extract a higher beam current from the FEL and to obtain a longer R-F pulse duration from the cavity.

The FEL Driven Two- Beam Accelerator Studies at CESTA
During the past few years, a demonstration that a free electron laser driven by an induction accelerator can furnish an intense bunched beam for use in a two-beam accelerator has been performed at CESTA. Earlier work, which concentrated on observing bunching by optical means, and the more recent production of R-F power obtained by passing the bunched beam through a standing-wave output cavity w...
متن کاملResults on the Interaction of an Intense Bunched Electron Beam with Resonant Cavities at 35 Ghz
The Two-Beam Accelerator (TBA) concept is currently being investigated both at Lawrence Berkeley National Laboratory (LBNL) and at CERN. As part of this program, a 7 MeV, 1-kA electron beam produced by the PIVAIR accelerator at CESTA has been used to power a free electron laser (FEL) amplifier at 35 GHz. At the FEL exit, the bunched electron beam is transported and focused into a resonant cavit...
متن کاملThe Jefferson Lab 1 Kw Ir Fel
The Jefferson Lab (JLab) IR Demo Free Electron Laser (FEL) has completed commissioning and is initiating user service. The FEL — a high repetition rate, low extraction efficiency wiggler-driven optical cavity resonator — produces over 1 kW of tuneable light on intervals in a 3–6 μm wavelength range. It is driven by a 35–48 MeV, 5 mA superconducting RF (SRF) based energyrecovering continuous wav...
متن کاملThe Linac Coherent Light Source (lcls) Accelerator∗
The Linac Coherent Light Source (LCLS) is a SASE xray Free-Electron Laser (FEL) based on the final kilometer of the Stanford Linear Accelerator. Such an FEL requires a high energy, high brightness electron beam to drive the FEL instability to saturation. When fed by an RF-photocathode gun, and modified to include two bunch compressor chicanes, the SLAC linac will provide such a high quality bea...
متن کاملSeeded FEL Microbunching Experiments at the UCLA Neptune Laboratory
Seeded high-gain FELs, which can generate very powerful radiation pulses in a relatively compact undulator and simultaneously modulate the electron beam longitudinally on the seed wavelength, are important tools for the advanced accelerator development. A single-pass 0.5-9 THz FEL amplifier-buncher driven by a regular photoinjector is being built at the UCLA Neptune Laboratory. FEL interactions...
