We report measurements of very large output intensities corresponding to a gain larger than 10 5 for a single pass free-electron laser operating in the self-amplified spontaneous emission (SASE) mode at 12 mm. We also report the observation and analysis of intensity fluctuations of the SASE radiation intensity in the high-gain regime. The results are(More)
We present the status of Saturnus : an infrared FEL operating in the 10 [Lm wavelength region, driven by a compact 20 MeV lmac with a photomlector, under construction at UCLA. The 1 .5 cm period, 0.5 T peak-field undulator is being built at the Kurchatov IAE. The FEL is being designed to operate primanly in the self-amplified spontaneous emission mode. We(More)
Energy gain of trapped electrons in excess of 20 MeV has been demonstrated in an inverse-free-electron-laser (IFEL) accelerator experiment. A 14.5 MeV electron beam is copropagated with a 400 GW CO2 laser beam in a 50 cm long undulator strongly tapered in period and field amplitude. The Rayleigh range of the laser, approximately 1.8 cm, is much shorter than(More)
We report on the observation of energy gain in excess of 20 MeV at the Inverse Free Electron Laser Accelerator experiment at the Neptune Laboratory at UCLA. A 14.5 MeV electron beam is injected in a 50 cm long undulator strongly tapered both in period and field amplitude. A CO 2 10.6 µm laser with power > 400 GW is used as the IFEL driver. The Rayleigh(More)
Saturnus is an infrared FEL operating in the 10 jim wavelength region, driven by a compact 20 MeV linac with a photoinjector, under construction at UCLA. The 1.5 cm period, 0.6 T peak field undulator is being built at the Kurchatov IAE. The FEL is designed to operate primarily in the self amplified spontaneous emission mode. We plan to study the start-up(More)
