Abstract65691 Extremely bright, affordable, photocathode electron sources are required for future DOE facilities such as the Next Linear Collider and Next Generation Light Sources. An electron gun with greater than 1 nC per bunch and less than 1 p mm-mrad normalized transverse rms emittance would meet this need, but the sub 1 p mm-mrad target remains elusive. Because axisymmetry has been shown to be important for minimizing emittance growth, this project will develop an axisymmetric electron gun that optimizes the standard emittance-compensation technique to break the 1 p emittance barrier. Phase I will complete the radio frequency design of the emittance-compensated gun, conduct beam dynamics modeling to refine emittance compensation, and determine the expected performance of a complete injector system. A prototype gun will be fabricated and tested in Phase II. Commercial Applications and Other Benefits as described by awardee:The electron gun should serve as the injector for advanced, high-brightness X-ray sources for both medical and protein crystallography applications. In the medical market the ability of a monochromatic, tunable, x-ray source to deliver much clearer diagnostic images with a much smaller dose fraction would be extremely attractive for such applications as breast cancer screening. In the pharmaceutical and biomedical industries, a compact high-performance protein crystallography unit would find application in the production of ¿designer drugs¿ and in the ongoing task of mapping and DNA sequencing the human genome.
