Abstract
We describe the status and initial commissioning of the Visible to Infrared SASE Amplifier (VISA) experiment. VISA uses a strong focusing 4 m undulato r, the Brookhaven National Laboratory ATF linac with an energy of 72 McV, a nd a photoinjector electron source. The VISA fundamental radiation waveleng th 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 comput er simulation. In addition, the induced electron beam micro-bunching will b e measured using coherent transition radiation. (C) 2000 Published by Elsev ier Science B.V. All rights reserved.
