Cryogenics at the Extremely Large Telescope (ELT)

Jakob, Gerd

Abstract:
The European Southern Observatory (ESO) is building the Extremely Large Telescope (ELT), a 40-m class telescope to be installed on top of the 3046 m high mountain Cerro Armazones in the central part of Chile's Atacama Desert. Once being operational around 2025, the ELT will be the largest optical/near-infrared telescope in the world, gathering 13 times more light than the largest optical telescopes existing today. “The world's biggest eye on the sky” will vastly advance astrophysical knowledge by enabling detailed studies of planets around other stars, the first galaxies in the Universe, super-massive black holes, and the nature and distribution of dark matter and energy which dominate the Universe. Powerful facility instruments are under development that can deliver the science cases for the ELT. The first instrument roadmap is listing more than six scientific instruments, each of them in the 10 - 20 tons class. Three selected first-light instruments are currently in detailed design phase, a diffraction-limited near-infrared imager, a single-field near-infrared wide-band integral field spectrograph, and a mid-infrared imager and s ... mehr
