Abstract

The Vanderbilt University Free-Electron Laser Program is developing the capability to create near-monochromatic x rays for medical imaging and other purposes. For this experiment we feed-back the normal infrared FEL light to collide with the electron beam. This causes Compton backscattering of the incident photons which creates x rays. These x rays cannot feed an x-ray laser, but they have a collimated intensity and tunability which make them highly suitable for medical imaging. This paper is particularly focused on the x-ray beam transport to be used with this experiment. This transport must collimate the x-ray beam and re-direct it to match a beam chase located in the vault ceiling at a 40 degree angle to the electron beam axis. A brief description of the creation mechanism and x-ray beam properties are included.
