Abstract

Summarized are the works done at KEK to study the collective beam instabilities caused by the RF cavities in TRISTAN. The works include the higher-order mode loss, the longitudinal and transverse coupled-bunch instabilities and the single bunch fast instabilities for longitudinal and transverse motions. A design aim of 4 mA/bunch and two bunches per beam can be achieved when feedback systems for longitudinal and transverse dipole oscillations are used. The other cures such as the higher-harmonic cavities, the wigglers, the couplers and the change of radiation damping partititon numbers are also desirable.
