Measuring Fel Radiation Properties at Visa-fel
The VISA (Visible to Infrared SASE Amplifier) SASE free electron laser has been successfully operated at the Accelerator Test Facility (ATF) at BNL. High gain and saturation were observed at 840 nm. We describe here the diagnostic system, experimental procedures and data reduction algorithms, as the FEL performance was measured along the length of the undulator. We also discuss selected spectra...
متن کاملChirped Pulse Amplification of HGHG-FEL at DUV-FEL Facility at BNL
The DUV-FEL facility has been in operation in High Gain Harmonic Generation (HGHG) mode for one year producing 266 nm output from 177 MeV electrons. In this paper we present preliminary results of the Chirped Pulse Amplification (CPA) of HGHG radiation. In the normal HGHG process, a 1 ps electron beam is seeded by chirped 9 ps long 800 nm Ti:Sapphire laser. The electron beam sees only a narrow ...
متن کاملMeasurements of Fel Polarization at Fermi
We report detailed quantitative characterization of different polarization states of a single-pass, externallyseeded FEL operating with variable polarization undulators in the VUV spectral range. The experiment has been performed at FERMI FEL-1 operated in the 52–26 nm wavelength range. Three different, independent polarimeter setups, installed at the end of experimental beamlines, have been us...
متن کاملFirst SASE and seeded FEL lasing of the NSLS DUV FEL at 266 and 400 nm
The Deep Ultra-Violet Free Electron Laser (DUVFEL) at the National Synchrotron Light Source consists of a 5MeV photoinjector, a 200MeV S-band linear accelerator, a four-magnet chicane compressor and a 10m wiggler with a 3.9 cm period. The commissioning of the SDL accelerator was completed recently and it is routinely producing a highquality electron beam with a peak current of B400A and a norma...
متن کاملFuture Fel Studies at the Visa Experiment
The VISA (Visible to Infrared SASE Amplifier) experiment at BNL (Brookhaven National Laboratory) has previously demonstrated saturation at 840 nm in 2001. Further SASE studies, in 2003, have demonstrated an anomalously large bandwidth spread of the FEL spectrum due to offangle emissions. This paper disseminates the current and future program of the VISA experiments at BNL. This includes a study...
