Abstract

The High Efficiency and Resolution Multi-Element spectrograph (HERMES) currently under construction at the Australian Astronomical Observatory will be the next major instrument for the Anglo-Australian Telescope. It will provide a unique and powerful new facility for multi-object spectroscopy. HERMES uses the 2dF fibre positioning system to provide up to 392 multiplex capability over a 2 degree field of view. The spectrograph design includes 4 wavelength channels, each with VPH-gratings providing a nominal spectral resolving power of 28,000 and a high-resolution mode of 50,000. The initial wavelength channels are tailored for determining a large range of chemical elements suitable for chemical tagging, but allow for grating upgrades reconfigurable between 370 - 1000 nm. An overview of the project and expected performance based on the HERMES simulated data is presented.
