MANIFEST

MANIFEST is a facility multi-object fibre system for the Giant Magellan Telescope.

MANIFEST will consist of several hundred of fibre buttons across the full telescope 20 arcmin FOV with an initial deployment across a 14-arcmin field of view.

MANIFEST will feed currently planned optical spectrographs (high resolution GCLEF and medium resolution GMACS) and future spectrographs (possibly including infrared spectrographs). MANIFEST baseline concept uses a pick-and-place robot system, and it will have multiple fibre configurations, ranging from single fibres to multiple integral-field units to single integral-field-units.

The MANIFEST instrument aims to enhance the functionality of the GMT spectrographs by offering capabilities such as: increasing the field of view, providing a moderate to a high degree of multiplex capability, multiple deployable IFUs, increased spectral resolution and/or wavelength coverage via image-slicing, the opportunity for simultaneous observation with multiple instruments, the possibility of a gravity-invariant instrument mounting, and the versatility of adding new instruments in the future.
