Abstract :
To satisfy the need of users of the synchrotron radiation at SRRC, the photon flux at the end station has to be kept at a constant with minimum fluctuation. The sources of flux variation attributable to the electron beam in the storage ring have been carefully studied and the effects on the flux have been investigated. The sources include floor vibration, power supply ripples, cooling water, ion trapping and transverse instability. The cures attempted or in plan include removal of vibration sources, reduction of ripple, local orbit feedback, ion cleaning and damping. A special diagnostic beamline has been constructed and used solely for accelerator studies and improvements
