This item was taken from the IEEE Periodical ' The Vanderbilt University Compton scattering X-ray experiment ' The Vanderbilt University Free-Electron Laser Program is developing the capability to create near-monochromatic X-rays for medical purposes. For this experiment we feedback 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 will make them highly suitable for medical imaging and therapy. This paper reviews the present design of the experiment and focuses on the X-ray beam transport to be used. This transport must re-direct the X-ray beam to match a beam chase located in the vault ceiling at an angle of 40 degrees with respect to the electron, beam axis. A description of the creation mechanism, X-ray and electron beam properties are included.<>
