  • Abstract
    An upgrade plan of the KEK B-Factory (KEKB), Super KEKB (SKEKB) has been discussed in KEK. The R&D of main vacuum components for the SKEKB, such as beam ducts, bellows chambers and connection flanges etc., are now undergoing. Trial models of a beam duct with an antechamber and a bellows chamber with a comb-type RF shield were installed in the KEKB positron ring and tested with beam. Coatings with a low secondary electron yield were also investigated with the positron beam. A special connection flange with small impedance was examined in a test bench.
