The crab cavities are presently being installed in the KEKB rings to compensate the crossing angle at collision and thus increase luminosity. This will be the first experience with such cavities in colliders. Results on the beam operation of the new cavities, both for single and colliding beams, will be presented including the luminosity performance and limitations.
Work presented on behalf of the KEKB Accelerator Group.

Under the leadership of KEK, the collaborating design activity has been performed in KEK in order to develop the STF (Superconducting RF Test Facility) cryogenic system, together with some positive Japanese industrial members. As the first activity of the collaboration, the initial plant of STF cryogenic system with capacity of 30W at 2.0K has been constructed for the testing of STF cryomodule, and been ready for its operation in KEK. In this session, the present status and schedule of STF cryogenic system in KEK shall be briefly reported.

Beam operation with crab cavities is planned in early 2007 at KEKB. The crab crossing scheme is expected to increase the vertical beam-beam tune-shift parameter significantly. One crab cavity will be installed in each ring where conditions for beam optics are matched to compensate the beam crossing angle of 22 mrad. Operation results on collision tuning with the crab cavities will be presented.
