An orbit feedback system around the interaction point (IP) has been developed and successfully employed at KEKB for more than 6 years. The purpose of the system is to maintain an optimum geometrical relationship of orbits of two beams at the IP and to prevent a luminosity degradation due to orbit drifts. The feedback system is based on orbit measurements around the IP rather than a direct measurement of the luminosity. Owing to the system, the luminosity degradation due to the orbit drifts is suppressed to around or less than 1%.

A novel design of a movable mask (collimator) for high-current accelerators is proposed. The mask head is supported by a ceramic rod to reduce interference with the beam. One side of the support is coated with a thin ( 1 m) conductive material to avoid extra charge up of the head. The head is also made of ceramics to avoid direct damage from an intense beam. To investigate the availability of the new movable mask, the rf properties, such as the impedances of trapped modes and the loss factors, were evaluated by simulation codes. The frequencies and the Q values of the trapped modes were also measured using a test model, and compared with calculated ones. Two trial modes for KEKB are being manufactured, and will be tested with beams next year.
