Thirty Meter Telescope science instruments: a status report

Abstract: An overview of the current status of the science instruments for the Thirty Meter Telescope is presented. Three first-light instruments as well as a science calibration unit for AO-assisted instruments are under development. Developing instrument collaborations that can design and build these challenging instruments remains an area of intense activity. In addition to the instruments themselves, a preliminary design for a facility cryogenic cooling system based on gaseous helium turbine expanders has been compl… Show more

“…These science goals are important drivers for all 30-meter class telescopes planned for the 2020s, i.e. the Extremely E-mail: dmilakov@eso.org Large Telescope (ELT, Tamai et al 2018), the Thirty Meter Telescope (TMT, Simard et al 2016), and the Giant Magellan Telescope (GMT, Fanson et al 2018). This is why all will be equipped with a high resolution optical spectrograph.…”

“…The Habitable Exoplanet Observatory 3 and the Large UV Optical Infrared Surveyor 4,5 (LUVOIR) are two space-based concepts recently studied by NASA as possible future flagship missions. Their primary science objective is the direct detection and spectral characterization of habitable Earth-like planets 6 and the search for life; they require primary mirror diameters of 4 to 15 m. Meanwhile, the ground-based community is preparing for the era of Extremely Large Telescopes (ELTs) where 30-to 40-m class telescopes such as the Thirty Meter Telescope 7 (TMT), the Giant Magellan Telescope 8 (GMT), and the European Extremely Large Telescope 9 (E-ELT) will be equipped with coronagraphs and extreme adaptive optics systems to search for and characterize exoplanets. 10 What unites all of these observatories is that they have significantly larger primary mirrors than their respective space-based and ground-based predecessors.…”

“…The first light Adaptive Optics (AO) architecture for the TMT [1] has been defined to provide near-diffraction-limited wavefront quality and high sky coverage in the near infra-red (IR) for the first TMT science instruments IRIS (InfraRed Imaging Spectrograph) and IRMS (InfraRed Multislit Spectrometer) [2], [3] . It is a Laser Guide Star (LGS) Multi Conjugate AO (MCAO) architecture consisting of (i) the Narrow Field IR AO System (NFIRAOS) [4] , which feeds up to three science instrument ports after sensing and correcting for wavefront aberrations introduced by the atmospheric turbulence and the telescope itself, (ii) the Laser Guide Star Facility (LGSF), which generates multiple LGS in the mesospheric sodium layer with the brightness, beam quality and asterism geometry required by both NFIRAOS and later the second generation of TMT AO systems, and (iii) the Adaptive Optics Sequencer of the AO Executive Software, which automatically coordinates the operations of the AO systems with the remainder of the observatory for safe and efficient observations.…”
