Who Am I?
[edit]My name is Bill Gabella and I am a physicist at Vanderbilt Univeristy's W.M. Keck Free-electron Laser Center. I currently help support the free-electron laser, but spend most of my time running, maintaining and using a Compton back-scattered tunable xray source. We collide a 10J, 5ps, 1053nm laser pulse with a 5ps long electron bunch with 10^9 electrons and an energy from 20 to 50 MeV. The part of the collision we are interested in is the 20 to 50 keV xrays that come out of the collision. That xray pulse, also about 5ps, is an energy spread of a few per cent, so it is nearly monochromatic.
