As discussed at the CASCA meeting, the Maunakea Spectroscopic Explorer (MSE) project has just wrapped up a series of subsystem conceptual design reviews.

Video of the Telescope Structure Conceptual Design

The conceptual design for MSE’s telescope structure by the Spanish firm IDOM has passed its review with flying colours. The 11.25m aperture MSE will fit within a structure only slightly wider than currently exists at CFHT. Details and a video of IDOM’s mount for MSE are available at this link.

More Conceptual Design Reviews

Many MSE partners and work packages delivered conceptual designs for review in Waimea and elsewhere this quarter:

  • Enclosure (Empire Dynamic Structures), held in Port Coquitlam, BC.
  • High Resolution Spectrograph (NIAOT, Nanjing). The Project Office welcomed the NIAOT team, including the Director of NIAOT, for this 2 day review.
  • Fiber Positioning Systems (a competitive study between teams from AAO, UAM and USTC).
  • Fiber Transport System (Herzberg Institute together with Fibertech Optica, Canada).
  • Real Time Software Architecture (staff at CFHT).
  • Top-End Assembly (INSU-DT and GEPI, France).
  • Low Resolution Spectrographs (CRAL, France) in Lyon, France.

With the completion of the subsystem conceptual design reviews, the next step is to undertake a project-wide system conceptual design review and then a cost review. The Project Office staff are now shifting gears from reviewing designs to preparing material for review, and plan to defend the system design in the last quarter of 2017.

Other Activities

The MSE Management Group held its 2017Q1 meeting by telecon. The components of a Design Phase Master Agreement are under discussion. Such an agreement would spell out past and planned pre-construction contributions from each partner and the corresponding science return in terms of access to MSE survey data as compensation for those contributions.

Canadian astronomers with questions or comments about MSE or MSE governance can contact their MSE MG members, Greg Fahlman and Pat Hall).

The MSE Science Advisory Group began the year by reviewing the MSE Science Requirements Document and prioritizing the first light science capabilities for a nominal 2026 first light. The results of this discussion by the SAG will inform the prioritization of different system elements in the upcoming project-wide system conceptual design and cost reviews.
