GHOST Update

The GHOST beamsplitter, fold mirror, and two gratings mounted in their cells at NRC-H.

There is good news from National Research Council Canada Herzberg (NRC-H). The Gemini High-resolution Optical SpecTrograph (GHOST) team recently bonded and mounted four major GHOST optical assemblies: the beamsplitter, fold mirror, and both red and blue gratings. The team is on track to start integrated testing at NRC-H in May, bringing in the optical cable from the Australian Astronomical Optics – Macquarie (AAO) and software from the Australian National University (ANU). The team also completed commissioning of the AAO-developed fiber positioner and optical cable, including ANU and Gemini software, at Gemini South in November.
