Status and initial commissioning of a high gain 800 nm SASE FEL
نویسندگان
چکیده
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 measurements are planned for the VISA radiation and these results will be analyzed and compared with SASE FEL theory and computer simulation. In addition, the induced electron beam micro-bunching will be measured using coherent transition radiation. ( 2000 Published by Elsevier Science B.V. All rights reserved.

Initial gain measurements of an 800 nm SASE FEL, VISA
The Visible to Infrared SASE Amplifier (VISA) FEL is designed to obtain high gain at a radiation wavelength of 800 nm. The FEL uses the high brightness electron beam of the Accelerator Test Facility (ATF), with energy of 72MeV. VISA uses a novel, 4m long, strong focusing undulator with a gap of 6mm and a period of 1.8 cm. To obtain large gain the beam and undulator axis have to be aligned to be...

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 کاملSaturation Measurements of a Visible Sase Fel*
VISA (Visible to Infrared SASE Amplifier) is an FEL designed to obtain high gain at a radiation wavelength of 800 nm. Large gain is achieved by driving the FEL with the 71 MeV, high brightness beam of the Accelerator Test Facility (ATF) and using a novel, strong focusing, 4 m long undulator with a gap of 6 mm and a period of 1.8 cm. We report measurements of exponential gain, saturation, and sp...
متن کاملCharacterization of an 800 nm SASE FEL at Saturation
Visible to Infrared SASE Amplifier is a free electron laser (FEL) designed to saturate at a radiation wavelength of 800 nm within a 4m long, strong focusing undulator. Large gain is achieved by driving the FEL with 72MeV, high brightness beam of BNL’s accelerator test facility. We present measurements that demonstrate saturation in addition to the frequency spectrum of the FEL radiation. Energy...

We propose a concept for production of high power coherent attosecond pulses in X-ray range. An approach is based on generation of 8th harmonic of radiation in a multistage HGHG FEL (high gain high harmonic free electron laser) configuration starting from shot noise. Single-spike phenomena occurs when electron bunch is passed through the sequence of four relatively short undulators. The first s...
