Abstract :
In the beam transport lines from the injector linac to KEKB rings, four wire scanners were installed for each of positron and electron line. The vibrations and non-linearities of the wire holders were suppressed to be small enough for beam size measurements. Optics matchings were made wing the wire scanners. Better transmission from the linac to the rings was obtained. By detecting shower due to Bremsstrahlung near the detector, the beam sizes were successfully measured without any beam tunings dedicated for background
