Figure 2. The GHOST team (consisting of members from AAO, NRC-H, ANU, and Gemini)successfully passed their Preliminary Design Stage Review at Gemini North Hilo headquarters on Wednesday. A team of dedicated experts, external and internal to Gemini, supported the review and made some very good suggestions to help keep the project on track. The entire team was happy and relieved on completion of this major project milestone. 16 prove GRACES’ performance and make it operate more efficiently. The expected sensitivity is already impressive, as illustrated in Figure 1. Since its 270-meter fiber, which connects Gemini to the CFHT ESPaDOnS spectrograph, has a high transmission between 500 and 900 nanometers, GRACES’ performance will rival that of other high-resolution spectrographs on other 8-10 meter telescopes. GRACES will operate in two modes: One offering an average resolution power of R=40,000, and another delivering R=68,000. Additional information can be found on the GRACES webpage here . GIFS Moves Ahead The Gemini Instrument Feasibility Study (GIFS) proposal deadline passed on December 15th with eight proposals received. GIFS will provide science cases and instrument ideas that could be used for the next facility instrument (Gen4#3). Gemini will now evaluate the proposals for selection in January, 2015. There’s still time, however, to provide input for Gen4#3 at the Gemini Future and Sci- GeminiFocus ence meeting in June. (Information about the meeting is available at this website). The latest information on GIFS can be viewed here. GHOST Materializing During the third week of December 2014, the Gemini High-resolution Optical SpecTrograph (GHOST) project held its Preliminary Design Review (PDR) in Hilo, Hawai’i (Figure 2). Attending were the Review Committee and several members from the partnership: Gemini Observatory, Australian Astronomical Observatory, Australian National University, and Canada’s National Research Council–Herzberg. The PDR Committee was pleased to see the progress achieved, acknowledging the extraordinary effort of the GHOST team in achieving the PDR’s passage and has recommended that the project proceed into the Critical Design Stage. The Committee also made numerous recommendations to help the team ensure success. Watch for future updates as the Critical Design Review approaches by the end of 2015; we still plan on January 2015
