Abstract:

A Laser Synchrotron Source LSS was proposed to generate short-pulsed, tunable x-rays by Thomson scattering of laser photons from a relativistic electron beam. A proof-of-principle p.o.p experiment on this LSS configuration is performed. An intense laser pulse Lambda sub 0 1.053 micrometers is Thomson backscattered from a focussed relativistic electron beam. Time integrated x-ray signals from a photocathodeelectron multiplier, at an electron beam energy of 650 keV and an x-ray photon energy of 20 eV, indicate an increase in the x-ray signals above the baseline by an amount comparable to the theoretically predicted value. This is the first observation of x-rays in the tens of eV range generated by the Thomson scattering of near infrared photons from a relativistic electron beam.
