Abstract
Many Free Electron Lasers (FELs) utilize high current, high energy electron beams. Inevitably, a small fraction of the electrons in the beam will exist outside the core beam; these electrons are referred to as beam halo. The halo electrons will travel down an FEL's transport system with the core electrons; any portion of those halo electrons that intercept transport system components can generate radiation that is harmful to the operating personnel. The amount of shielding that is required to keep personnel safe from radiation exposure is evaluated as a function of the lost halo current. Using the modeling software FLUKA, an analysis is presented describing the amount of necessary shielding for a given shielding material.
