  In May 2012 the Australian Synchrotron commenced Top-Up Operations for User beamtime. The facility was designed for top-up from the start with a full energy 3 GeV injection system, however top-up only became a priority once the beamline user community had established itself at the new facility in operation since April 2007. New beam diagnostic and equipment protections systems were implemented as part of the move to top-up, including a new injection efficiency monitoring system. The effect of top-up on the beamline data was also tested with each beamline prior to engaging top-up during user runs. Top-up has now been running successfully for one year and the performance statistics from this period will be presented. Top-up operations is a very popular standard mode for user beam and falling into decay mode is now treated almost as a beam dump.

  Magnet misalignments give rise to field terms which can cause coupling between the horizontal and vertical beam motion and therefore emittance coupling. A series of beam based measurements have been developed at the Australian Synchrotron to accurately quantify quadrupole and sextupole alignments errors which cause coupling and where possible, correct them. Results showing an reduction in emittance coupling due to realignments of magnets based on these measurements will be presented. Limitations and general applicability of this method will also be discussed.
