The 3GeV Australian Synchrotron will begin operation in March 2007. This paper outlines the tune and lifetime measurement systems. It also provides a summary of a number of studies completed using these systems. Three different tune measurement systems have been tested. Lifetime measurements made using the DCCT were used to optimise the strengths of the harmonic sextupoles and the location of the tunes. The vertical aperture was determined using scrapers. Beta-function measurements have been completed by shunting individual quadrupoles and noting the resultant tune changes. Chromaticity measurements have been made by observing the change in tune as the RF frequency is varied.

The Australian Synchrotron (AS) is equipped with a full compliment of 98 BPMs attached to Libera Electron Beam Position Processors (EBPPs) that are capable of measuring turn-by-turn/first turn and averaged beam positions simultaneously. The BPM system coupled with Matlab applications has simplified the process of commissioning. This report will highlight how the various tools have been utilised and show the results of some studies.

First Light has been achieved on the diagnostic beamlines at the Australian Synchrotron 3 GeV storage ring. The X-ray Diagnostic Beamline (XDB) has been used to measured the beam size, divergence and emittance, while the Optical Diagnostic Beamline (ODB) has been used the measure the bunch length and turn-by-turn stability. Both beamlines receive dipole radiation from a bend magnet and provide continuous diagnostic data to the control room. The beamlines compliment each other with the ODB providing mainly longitudinal (temporal) information, while the XDB measures predominantly transverse (spatial) information. A brief description is given of the equipment on each beamline and the commissioning results are presented.
