title = "New-generation hexabundles: development and initial results",
abstract = "The original optical fibre imaging bundles called hexabundles' have proven to be exceptionally efiective in the Sydney-AAO Multi-object IFS (SAMI) instrument, enabling one of the worlds largest IFS galaxy surveys5, 6 . We are now developing an improved next-generation hexabundle design. These IFUs use a novel assembly technique developed in the Sydney Astrophotonic Instrumentation Laboratories (SAIL) at the University of Sydney, that enable very high ll-fraction and an evenly distributed, hexagonally packed, array of 217 fibre cores. These new hexabundles will see first light in 2019 on the new Hector-I instrument for the Anglo-Australian Telescope (AAT). The large number of fibre cores will measure spatially-resolved spectroscopy of galaxies out to 2 efiective radii. The hexabundles are currently being prototyped, and characterised. The impact of the hexagonal packing of the fibre cores on Focal Ratio Degradation (FRD), total throughput of the device and overall performance will be presented.",
