Abstract The ADS beamlines are the fifth and sixth beamlines being built within the Australian Synchrotron/ANSTO BRIGHT program The two beamlines (ADS-1 and ADS-2) will operate independently with the beam generated by a powerful super-conducting multipole wiggler (SCMPW). ADS-1 will have tunable collimating optics that will combine with a fixed exit double crystal Laue monochromator (DCLM) to provide white, pink and monochromatic beam (50-150 keV) to a large end-station located outside the main synchrotron building. ADS-1 will accommodate experiments using a variety of sample stages capable of positioning large and heavy samples (up to 300 kg). The second ADS beamline, ADS-2, will take a deflected beam from the main beam using a side-bounce monochromator (SBM) that produces three monochromatic energies from 45 keV - 90 keV. The SCMPW source for the beamline produces a beam of 45 kW at 4.5 T. The major optics of the beamline include a cryogenic SBM and a cryogenic DCLM, a transfocator and multilayer VFM. The high heat load on the front end and upstream monochromator represented key challenges for the beamline design. Innovative approaches to thermal management have been developed. The high radiation environment required additional safety protocols to be implemented for beamline operation. The primary beamline endstation utilises a large gantry robot to independently position up to 4 detectors in an envelope of up to 8x3x0.3 m with a positional repeatability of ± 0.01 mm. The large motion envelope gives users access to large Q-range and allows flexibility for users to utilise large bespoke sample environments. The ADS beamlines project encompasses design, procurement, build/installation and commissioning phases. The beamline will commence user operations in July 2023.
