Abstract

The Australian Synchrotron storage ring has a high resistive wall impedance in the vertical plane. Presently the instability from this impedance is being controlled by increasing the vertical chromaticity. However new in-vacuum insertion devices that significantly increase the ring impedance will demand chromatic corrections beyond the capabilities of the sextupole magnets. A transverse bunch-by-bunch (BBB) feedback system has been commissioned to combat the vertical instability and provide beam diagnostics. A high frequency narrow band mode that could not be damped was initially encountered with IVUs at specific gaps preventing the system from being implemented during user beam. Study into the lattice has lead to a configuration of the sextupoles that can be used for user operations.
