Second Generation Instruments

Second Generation Instrumentation

See the original call for TMT Instrumentation White Papers (deadline for submission was March 21, 2018).

Currently the main instruments foreseen to be operational at first-light are WFOS and IRIS. Any other facility-instruments planned afterwards are part of the “next-generation” suite of instruments.

The TMT Science Advisory Committee (SAC) had released a call for White Papers for next-generation instrument capabilities. In addition, the 2017 TMT Science Forum, which was held in Mysore, India from November 7-9 (, was dedicated to forming the teams to kick off the concept studies for the next generation of TMT instruments. Some of these efforts have already started over the past years, which led to the identification of instruments with specific capabilities:

  • A mid-infrared spectra-imager instrument. The current concept is named ‘b-MICHI’ with lead scientist, Chris Packham (,
  • A high-contrast instrument for detecting and characterizing the atmospheres of exoplanets (concept named 'PFI' for Planet Formation Instrument),
  • A high-resolution spectrograph in the visible domain (HROS), or near-infrared (NIRES),
  • Multi-object medium-resolution spectrographs in the near-IR such as IRMS and IRMOS.

These instrument concepts were explored at the TMT Science Forum held in India in November 2017. An outcome of this Forum was to respond to the call for White Papers on TMT next generation instrumentation, which will lead to launching feasibilities studies later in 2018 for all concepts ranked as top-priority by the TMT Science Advisory Committee.
