Crescent MOONS: an update on the ongoing construction of the new VLT's multi-object spectrograph
Ground-based and Airborne Instrumentation for Astronomy VIII(2020)
摘要
The Multi Object Optical and Near-infrared Spectrograph (MOONS) instrument is the next generation multi-object spectrograph for the VLT. This powerful instrument will combine for the first time: the large collecting power of the VLT with a high multipexing capability offered by 1000 optical fibres moved with individual robotic positioners and a novel, very fast spectrograph able to provide both low- and high-resolution spectroscopy simultaneously across the wavelength range 0.64 mu m - 1.8 mu m. Such a facility will provide the astronomical community with a powerful, world-leading instrument able to serve a wide range of Galactic, Extragalactic and Cosmological studies. The final assembly, integration and verification phase of the instrument is now about to start performance testing.
