Measuring Fel Radiation Properties at Visa-fel

چکیده
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 spectral radiation measurements.

Results of the VISA SASE FEL Experiment at 840 nm
VISA (Visible to Infrared SASE Amplifier) is a high-gain self-amplified spontaneous emission FEL, which achieved saturation at 840 nm within a single-pass 4-m undulator. A gain length shorter than 18 cm has been obtained, yielding the gain of 2¥10 at saturation. The FEL performance, including spectral, angular, and statistical properties of SASE radiation, has been characterized for different e...
متن کاملInitial Gain Measurements of a 800nm SASE FEL, VISA
The VISA (Visible to Infrared SASE Amplifier) FEL is designed to obtain high gain at a radiation wavelength of 800nm. The FEL uses the high brightness electron beam of the Accelerator Test Facility (ATF), with energy of 72MeV. VISA uses a novel, 4 m long, strong focussing undulator with a gap of 6mm and a period of 1.8cm. To obtain large gain the beam and undulator axis have to be aligned to be...
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...
متن کاملStatus and initial commissioning of a high gain 800 nm SASE FEL
We describe the status and initial commissioning of the Visible to Infrared SASE Ampli"er (VISA) experiment. VISA uses a strong focusing 4 m undulator, the Brookhaven National Laboratory ATF linac with an energy of 72 MeV, and a photoinjector electron source. The VISA fundamental radiation wavelength is near 800 nm and the power expected at saturation is near 60 MW. Power, angular and spectral ...
متن کاملSASE FEL Saturation Characterization at the ATF
After successful completion of the High Gain Harmonic Generation (HGHG) free electron laser (FEL) experiment [1,2] at the Accelerator Test Facility (ATF), R&D toward future light sources at the NSLS achieved another milestone on March 17, 2001 when the visible-infrared self-amplified spontaneous emission amplifier (VISA) experiment at the ATF achieved saturation. The VISA Self Amplified Spontan...
