Currently, the Free Electron Laser (FEL) at Thomas Jefferson National Accerator Facility (Jefferson Lab) is capable of lasing up to 1.7 kilowatts. Due to the geometry of the laser optical cavity, X-rays were predicted (by Krafft in 1997) and observed at the Vanderbilt FEL due to Thomson Scattering effects. It is my goal to aid in the design, calibration, and detection of these X-rays at Jefferson Lab. Fortunately the majority of the X-rays are produced at a slight angle to the IR and electron beam allowing us to diffract them off certain crystals into our detector. The data we hope and plan to obtain not only confirm theory, but also give sight into the actual shape and distribution of a single electron bunch.
