The normalized acceptance of the KEK booster has large value in horizontal plane (80 n mm mrad in the horizontal plane and 1871 mm mrad in the vertical plane). To increase the beam intensity we have been trying to achieve painting injection in the horizontal plane. The intensity-dependent emittance-exchanges in the horizontal and vertical plane were measured by a method using a scraper and bump magnets and extracted beam profiles measured by multiwire profile monitor.
