One diagnostic beamline is a simple x-ray pinhole camera system, with a BESSY II style pinhole array [2], designed to measure the beam divergence, size and stability. The second diagnostic beamline uses an optical chicane to extract the visible light from the photon beam and transports it to various instruments. The end-station of the optical diagnostic beamline is equipped with a streak camera, a fast ICCD camera, a CCD camera and a Fill Pattern Monitor to analyse and optimise the electron beam using the visible synchrotron light.

The X-ray Diagnostic Beamline (XDB) has been used to measure 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.

Beam loss detec-tion is particularly challenging due to the large extension of new facilities that need to be covered with localized detector. Candidates to mitigate this problem consist of systems in which the sensitive part of the radiation detec-tors can be extended over long distance of beam lines. In this document we study the feasibility of a BLM system based on optical f ber as an active detector for an electron storage ring. The Australian Synchrotron (AS) comprises a 216 m ring that stores electrons up to 3 GeV. The Ac-celerator has recently claimed the world record ultra low transverse emittance (below pm rad) and its surroundings are rich in synchrotron radiation. Therefore, the AS pro-vides beam conditions very similar to those expected in the CLIC/ILC damping rings....

The maximum acceptable amplitude of vibrations is small, as vibrations in the accelerating structure could lead to beam jitter and alignment difficulties. A Finite Element Analysis model is needed to identify the conditions under which turbulent instabilities and significant vibrations are induced. Due to

This paper will present the results of these studies and show the time evolutionof machineimpedancewith increasingnum- ber of insertion devices. OVERVIEW The Australian Synchrotron is a rd generation light source facility located in Melbourne, Australia. Commis- sioning was conducted in 2006, with beamline operations commencing in April 2007. The 3 GeV storage ring is 216 metres in circumference and can store a beam of up to 200 mA current. A design overview can be found in (1). The first phase of beamline development consists of 9 initial beamlines, 5 of which are currently in operation and the other 4 are in late stages of construction. Of these 9 beam- lines, 6 will use insertion devices (IDs), 3 being In-Vacuum Undulators (IVUs). Both kinds of insertion devices req...
