AAT Future Instrumentation Workshop (held on 9 November 2007, ATNF Lecture Theatre)

Workshop Objective

Workshop summary and conclusions by Matthew Colless, AAO Director
A community workshop was held on Friday, 9 November 2007, at the AAO Epping laboratory to discuss the various options for a new instrument at the Anglo-Australian Telescope (AAT).

The objective of this one-day workshop was to receive community input to the science objectives and requirements, and to prioritise these options.  The AAO will likely make a final decision on which option to pursue by the middle of 2008.

Funds from the NCRIS scheme for the development of a new instrument for the AAT have been used to look at a variety of instrument options, including AAOmicron (an infrared multi-object spectrograph expanding AAOmega to 0.9-1.7microns), HERMES (a High Resolution Multi-object Echelle Spectrograph) and WFMOS-A (a wide-field multi-object optical spectrograph using Echidna fibre positioning).

The workshop featured talks on the science drivers for each main instrument concept, the planned technical capabilities, and an extended discussion of the instrument options.
