IGRINS-2 has been delivered to Gemini North in September 2023 and successfully completed the first telescope integration run in early October. Once the telescope integration and commissioning is completed, IGRINS-2 will be offered to the Gemini User Community.
IGRINS-2 Overview
IGRINS-2 is a high-resolution near-infrared spectrograph (R~40,000; 1.49-2.46um), closely based on the original IGRINS (Immersion GRating INfrared Spectrograph). IGRINS-2 will become a Gemini North facility instrument, unlike IGRINS, which is a visiting instrument at Gemini South.
After successfully completing design review, the IGRINS-2 project is currently in the Telescope Integratio Stage led by the Korea Astronomy and Space Science Institute (KASI) in Daejeon, Korea. We are aiming to complete IGRINS-2 commissioning in mid-2024 and offering it to the Gemini science community in late 2024.
