Instrumentation upgrade for Top-Up operations at the Australian Synchrotron

Abstract

The Australian Synchrotron introduced Top-Up operations in May 2012. Upgrading the machine for Top-Up has required major developments in many of the accelerator systems. Investigations prior to the start of Top-Up operations demonstrated that the Infrared Microspectroscopy beamline was particularly sensitive to injection noise. A gating event has been implemented as part of our timing system upgrade to pause the data collection during injection. In Top-Up mode injections can happen when the gaps of insertion devices are closed. A variable vertical aperture has been installed in the BTS to scape potentially damaging electrons and protect the equipment. © 2013 IOP Publishing Ltd.
