| Abstract: | This paper is intended to present the newly implemented wideband(100 MHz) bunch oscillation measurement system,which is in nature a different method from the narrow-band(<5 MHz) facilities employed before.Basic formalism and implementation details of the system is introduced to illustrate the function of observing coupled bunch instabilities in time and frequency domain.The designed function includes detecting of transverse oscillation,synchrotron phase oscillation,as well as bunch filling pattern.Some diagnostics results of machine instabilities and application of this system are also discussed. |
