Title RESEARCH AND DEVELOPMENT PROGRAM ON SUPERCONDUCTING CRAB CAVITIES FOR KEKB
Type Poster new projects
Abstract Recent stable operation of the KEKB accelerator brings the highest integrated luminosity in the world and opens the new world of the particle physics. Then KEK has determined to install superconducting crab cavities into KEKB to obtain much more luminosity. Since no crab cavities have been operated in any accelerators so far, we had to started our research and development program on crab cavities for KEKB from the beginning literally. With 1/3-scale crab cavities made of pure niobium we had learned and experienced the fundamental characteristics of the crab cavities. As the second phase, we have fabricated two full-scale crab cavities and measured their performance. Beside these activities, various  special parts to the crab cavities, such as coaxial couplers, notch filters, stub supports are under development. Also we have started to design the cryostats which accommodate crab cavities in KEKB.
