Simulation Analysis of Head-Tail Motion Caused by Electron Cloud
/ Ohmi, Kazuhito ; Flanagan, John W ; Fukuma, Hitoshi ; Hiramatsu, Shigenori ; Ikeda, Hitomi ; Perevedentsev, Evgueni ; Tobiyama, Makoto
Synchro-beta side band caused by electron cloud instability has been observed at KEK-B factory. The side-band appears between $νβ+νs$ and $νβ+2νs$ above the threshold of beam size blow up and disappear by applying solenoid field. [...]

Betatron Sidebands Due to Electron Clouds Under Colliding Beam Conditions
/ Flanagan, John W ; Fukuma, Hitoshi ; Funakoshi, Yoshihiro ; Hiramatsu, Shigenori ; Ikeda, Hitomi ; Ohmi, Kazuhito ; Perevedentsev, Evgueni ; Tobiyama, Makoto ; Uehara, Sadaharu ; Uno, Shoji
Recently, we have observed vertical betatron sidebands in the transverse beam spectra of positron bunches at the KEKB LER which are associated with the presence of electron clouds. When the LER is operating in single-beam mode (no colliding bunches in the HER), these sidebands are sharply peaked. [...]

Movement of BPMs Due to Thermal Stress in KEKB
/ Tejima, Masaki ; Arinaga, Mitsuhiro ; Fukuma, Hitoshi ; Hiramatsu, Shigenori ; Ieiri, Takao ; Ishii, Hitoshi ; Tobiyama, Makoto
Movement of Beam Position Monitors (BPM) due to thermal stress in high beam current operation is observed in KEKB. For high luminosity operation of KEKB, the beam current as high as 1.6A is accumulated in the positron ring and a precise control of the beam orbit based on the BPM system is required. [...]

Vertical Beam Size Measurement by Streak Camera under Colliding and Single Beam Conditions in KEKB
/ Ikeda, Hitomi ; Flanagan, John W ; Fukuma, Hitoshi ; Funakoshi, Yoshihiro ; Hiramatsu, Shigenori ; Mitsuhashi, Toshiyuki ; Ohmi, Kazuhito ; Uehara, Sadaharu
Beam behavior of KEKB was studied by measurement of the beam size using a streak camera. Effect of the electron-cloud and the parasitic collision on the vertical beam size was examined in beam collision. [...]

Measurement of Dynamic Beam-Beam Effects on Horizontal Beam Size at KEKB Using SR Interferometer Equipped with Retrofocus Optics
/ Flanagan, John W ; Fukuma, Hitoshi ; Hiramatsu, Shigenori ; Mitsuhashi, Toshiyuki
Transverse beam-size enlargement due to dynamic beta and beam-beam effects has been observed in the KEKB Low Energy Ring (LER) and High Energy Ring (HER). In order to observe these effects, a retrofocus optics system has been developed and installed in the horizontal SR interferometers at the HER and LER. [...]
