Abstract :
To obtain a wide acceptance for the injected beam in the KEK-Photon factory (PF) storage ring, we designed and constructed a travelling wave kicker magnet and pulse power supply. The characteristic impedance of the magnet is designed to be 6.25 Ω. The magnet consists of a 30-cell structure. Since the magnet is set outside of the vacuum chamber, we apply a silicon rubber molding for insulation of the high voltage components. The magnet operates with a newly constructed power supply. To obtain a sufficient kick, we doubled the peak current by the use of a shorted end. The new kicker magnets were installed in the PF ring in January 2000, and have been successfully operated during injection
