主講人 (Lecturer)：Prof. Kazuhito Ohmi, KEK, Japan 

　　主持人 (Chair)：Prof. Jie Gao, IHEP 

　　講座題目 (Theme)：Electron cloud effects in KEKB and LHC 

　　內(nèi)容摘要 (Abstract)： 

　　Electron cloud instability was first observed at KEK-Photon factory as a strong instability in positron storage, and was identified as phenomena caused by electrons produced by synchrotron radiation in 1995. KEKB (start from 2000) suffers the instability, and achieves highest luminosity to overcome it finally. LHC has been observed the electron cloud effectsincreasing operating current and more bunches. 

　　The electron cloud effects in KEKB and LHC are reviewed. 

　　演講人簡(jiǎn)介 (Lecturer’s short bio): 

　　Prof. Ohmi obtained his PhD in hadron spectroscopy in \pe p interaction. He started accelerator research from 1990. Research subject is accelerator physics, especially, beam-beam effects, electron cloud effects, and space charge effects.
