Prior to the 1995 shutdown of the ELSA facility, we recorded our first time-resolved photon spectra. They clearly showed the chaotic behaviour predicted at high coupling but their low signal-to-noise and time resolution precluded a fine analysis. A n

The ELSA free-electron laser has delivered its first FEL photons at a wavelength of about 23 μm. Electron bunches were produced by a 144 MHz photoinjector, accelerated to 16.5 MeV by a 433 MHz linac and transported through a three-dipole U-turn into

The residual vacuum pressure of the 144 MHz RF-gun cavity has been improved significantly ( p r ≈ 5 × 10 −10 bar ). However, when running with RF power we still observe a vacuum degradation which is responsible for the limited photocathode lifet

A near-infrared FEL experiment (ELSA) based on a 20 MeV rf linac is being constructed at Bruyeres-le-Châtel. To reach high peak power, we have chosen nonstandard technologies, namely: a low-frequency photoinjector (144 MHz), a low-frequency accelera

Projectile-like fragments have been measured in 40 Ar induced reactions on 197 Au at 27, 35 and 44 MeV/u and on 103 Rh at 27 MeV/u. The excitation energies deposited in the associated target-like fragments have been estimated from multiplicities of c

To optimize the electron-beam energy extraction, high-quality wigglers are required with strong magnetic fields and a flexible tuning of the tapering. For that purpose, we have designed a hybrid wiggler with several permanent magnets per pole. Off-li
