Detailed magnet specifications, vacuum-chamber beam apertures, and diagnostic specifications have been developed for the recirculation arcs. Analysis of the stability of an RF control system based on CEBAF control modules indicates that only minor modifications will be needed to apply them to this FEL. We decided to use a wiggler from the Advanced Photon Source which leads to a robust high-gain FEL. A more compact lattice has been designed for the UV FEL, and a new recirculation scheme has been identified which greatly increases more » the threshold for longitudinal instabilities. A new injection method has reduced the longitudinal and transverse emittance at the linac entrance. More exact simulations of the injector have resulted in a more accurate estimate of the injector performance. Since then, we have progressed toward resolving several issues associated with that design. ![]() ![]() Last year we presented a design for a kilowatt industrial UV FEL based on a superconducting RF accelerator delivering 5 mA of electron-beam current at 200 MeV with energy recovery to enhance efficiency. Free Electron Laser (FEL), Pulsed Wire Method, High Energy Laser (HEL), Shipboard High Energy Laser, Theater Ballistic Missile Defense (TBMD). Data analysis indicates the wiggler will have a net electron beam deflection of x=5.2mm, which is much greater than the electron beam radius of re=0.4mm and the optical mode waist of wo=1mm. ![]() The remainder will focus on use of the pulsed wire more » method for measuring the magnetic field errors of the CEBAF/National Institute of Science and Technology (NIST) wiggler. 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 proposed infrared and ultraviolet FELs at the Continuous Electron Beam Accelerator Facility (CEBAF) have been projected to provide high average power. It is capable of providing wide tunability and high efficiency, but has yet to yield high average power required as a weapon system. The Free Electron Laser (FEL) has proven to be a versatile photon source for many applications in science, industry and defense.
