    Quest for the Legitimizing Jesus Deployment of a Contested Symbol by a Non-traditional Religious Movement

    There have always been alternative interpretations of Jesus throughout Christian history. The meaning of such a symbol is never static. However, a general theological consensus had maintained an essentially hegemonic position throughout much of the Christianized world for most of the centuries of the Common Era. Jesus as an authoritative religious symbol has been destabilized by modern scholarship. Popular books and movies that explore and experiment with variant interpretations have proliferated in recent years. This contested but still powerful symbol is reinterpreted and employed by many groups, including a non-Christian religious movement based in Salt Lake City. Even though this group does not employ the traditional meanings associated with Jesus, by constructing alternative interpretations they distinguish their identity boundaries with reference to the dominant culture, create plausibility for a different worldview, and lend legitimacy to their movement.College of Arts and Sciencesmonographi

    A High-Average-Power Free Electron Laser for Microfabrication and Surface Applications

    CEBAF has developed a comprehensive conceptual design of an industrial user facility based on a kilowatt ultraviolet (UV) (160-1000 mm) and infrared (IR) (2-25 micron) free electron laser (FEL) driven by a recirculating, energy recovering 200 MeV superconducting radio frequency (SRF) accelerator. FEL users, CEBAF's partners in the Lase Processing Consortium, including AT&T, DuPont, IBM, Northrop Grumman, 3M, and Xerox, are developing applications such as metal, ceramic, and electronic material micro-fabrication and polymer and metal surface processing, with the overall effort leading to later scale-up to industrial systems at 50-100 kW. Representative applications are described. The proposed high-average-power FEL overcomes limitations of conventional laser sources in available power, cost-effectiveness, tunability, and pulse structure

    As reported previously [1], Jefferson Lab is building a free-electron laser capable of generating a continuous wave kilowatt laser beam. The driver-accelerator consists of a superconducting, energy-recovery accelerator. The initial stage of the program was to produce over 100 W of average power with no recirculation. In order to provide maximum gain the initial wavelength was chosen to be 5 mu-m and the initial beam energy was chosen to be 38.5 MeV. On June 17, 1998, the laser produced 155 Watts cw power at the laser output with a 98% reflective output coupler. On July 28th, 311 Watts cw power was obtained using a 90% reflective output coupler. A summary of the commissioning activities to date as well as some novel lasing results will be summarized in this paper. Present work is concentrated on optimizing lasing at 5 mu-m, obtaining lasing at 3 mu-m, and commissioning the recirculation transport in preparation for kilowatt lasing this fall
