The Free Electron Laser (FEL) has proven to be a versatile photon source for many applications in science, industry and defense. It is capable of providing wide tunability and high efficiency, but has yet to yield the high average power required as a weapon system. The proposed infrared and ultraviolet FELs at the Continuous Electron Beam Accelerator Facility (CEBAF) have been projected to provide high average power. The first section of this thesis will study the necessity of a FEL for shipboard defense, and state the advantages over other defense systems. The remainder will focus on use of the pulsed wire method for measuring the magnetic field errors of the CEBAF/National Institute of Science and Technology (NIST) wiggler. Data analysis indicates the wiggler will have a net electron beam deflection of Ac = 5.2 mm, which is much greater than the electron beam radius of re ~ 0.4 mm and the optical mode waist of w - 1 mm.
