	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.

MOPAN037	Acceleration of Cold Emission Beam from Carbon Nanotube Cathode in KEKB/PF Linac	236
	S. Ohsawa, M. Ikeda, T. Sugimura KEK, Ibaraki Y. Hozumi Advanced Manufacturing Research Institute, Tsukuba
	An electron gun with carbon nanotube cathode has been installed in the KEKB/PF linac, and the beam acceleration tests up to 2.5GeV have been performed successfully. The results and performance are presented in details.
THPMN027	Status of C-band Accelerator Module in the KEKB Injector Linac	2769

	For future upgrade of the KEKB injector linac, components of C-band accelerator module have been developed since 2002. A prototype C-band accelerator module composed of a 50-MW klystron, an RF-pulse compressor and four 1-m long accelerating sections, has been constructed in the present S-band injector linac. It has been operated for 14 months. In a recent beam-acceleration study, it has achieved an energy gain of 151 MeV, which corresponds to an average acceleration field of 39 MV/m.
THPMN029	A DC/Pulse Electron Gun with an Aperture Grid	2775
	T. Sugimura, M. Ikeda, S. Ohsawa KEK, Ibaraki
	A new thermionic-electron gun for a high-brightness X-ray source is under development. Its extraction voltage and design current are 60 keV and 100 mA, respectively. In order to focus beams on a metal target within 1.0 x 0.1 mm², it is required for the emittance of a beam to be small. A grid electrode is not an orthodox mesh grid but an aperture grid. An increase of the beam emittance and heat generation at a grid will be surpressed. Electrodes dimensions such as shape of Wehnelt electrode and a shape of an aperture grid are determined by the EGUN simulation and parameters were optimized. In this paper a result of beam examination will be 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. For the KEKB Accelerator Group.
