Abstract: The fluoro-based polymer composite target for sputtering according to the present invention is excellent in adhesion with a metal electrode to which a voltage is applied, can prevent bending, and is capable of stably forming plasma by imparting conductivity even with industrially widely used DC and MF power supply systems, thereby allowing a fluorinated polymer to be effectively deposited on an adherend by sputtering.

Abstract: A method and mechanical design for a thin-film diamond crystal mounting apparatus for coherence preservation x-ray optics with optimized thermal contact and minimized crystal strain are provided. The novel thin-film diamond crystal mounting apparatus mounts a thin-film diamond crystal supported by a thick chemical vapor deposition (CVD) diamond film spacer with a thickness slightly thicker than the thin-film diamond crystal, and two groups of thin film thermal conductors, such as thin CVD diamond film thermal conductor groups separated by the thick CVD diamond spacer. The two groups of thin CVD film thermal conductors provide thermal conducting interface media with the thin-film diamond crystal. A piezoelectric actuator is integrated into a flexural clamping mechanism generating clamping force from zero to an optimal level.

Abstract: An ignition feedback regenerative amplifier consists of an injector, a linear accelerator with energy recovery, and a high-gain free electron laser amplifier. A fraction of the free electron laser output is coupled to the input to operate the free electron laser in the regenerative mode. A mode filter in this loop prevents run away instability. Another fraction of the output, after suitable frequency up conversion, is used to drive the photocathode. An external laser is provided to start up both the amplifier and the injector, thus igniting the system.

Abstract: The present invention relates to a fluorine-containing graft copolymer and its manufacturing method. In particular, the fluorine-containing graft copolymer synthesized by copolymerization of copolymerizable perfluoroalkyl compound as a main chain and macromonomer having copolymerizable vinyl group at one end as branched chains, respectively. Thus the graft copolymer has the remarkable affinity to the substrates designed for the surface modification and superior performance than random copolymers, when it is employed as various types of surface modifiers of fluorine-containing compounds (e.g., water and oil repellent, soil release agents, mold-releasing agents, etc.).
