2 Outline Overview of MSE as implementation of a wide-field multi-object spectroscopic survey facility Status of MSE design phase development MSE and its parts by using the Product Breakdown Structure Highlight fundamental engineering choices that shaped the MSE design Describe the sum of its parts in the conceptual design configuration State estimates of MSE s cost and timeline

3 Context MSE aims to transform CFHT into a 10m class spectroscopic survey facility Only large aperture wide-field MOS facility under development in the world At least a design phase ahead of similar facilities under consideration MSE development has completed Conceptual Design Phase. A total of $9M has been invested on CoDP, in-kind efforts and cash contributions. Technical details of the Conceptual Design is captured in the MSE 2018 book.

4 The Conceptual Design Phase culminated in January 2018 with a System Design Review to assess if the conceptual design meets the science requirements stated in the SRD. Based on the Level 1 documents and their supporting documents Conceptual Design Phase

5 Conceptual Design Phase The Conceptual Design Phase culminated in January 2018 with a System Design Review to assess if the conceptual design meets the science requirements stated in the SRD. Based on the Level 1 documents and their supporting documents The design review panel s assessment was very positive:.this project is in very good shape, and at an appropriate level of maturity for the end of the Conceptual Design Phase. We have been very impressed by the level of sophistication that the MSE project team has brought to this project, and the tremendous amount of hard work that has been carried out thus far. This level of professionalism bodes well for the project as it enters the Preliminary Design Phase.

6 Context MSE aims to transform CFHT into a 10m class spectroscopic survey facility Only large aperture wide-field MOS facility under development in the world At least a design phase ahead of similar facilities under consideration MSE development is starting Preliminary Design Phase. The PDP cost is estimated to be $25M $13M of in-kind contributions have been identified.

7 Preliminary Design Phase The PDP starts in 2019 with participants: Australian Astronomical Optics (AAO) Macquarie National Research Council (NRC) of Canada National Astronomical Observatories (NAOC), Chinese Academy of Sciences Centre National de la Recherche Scientifique (CNRS) of France Institute for Astronomy, University of Hawaii India Institute of Astrophysics National Optical Astronomy Observatory, USA and Texas A&M University participate as observers

8 Science Driven Design Product Breakdown Structure The science requirements and physical design of the MSE are linked by the Product Breakdown Structure. PBS represents the engineering implementation of the science requirements in actual hardware and software subsystems. PBS reflects the system architecture and design choices of the Project Office and design team.

9 PBS Philosophy Our engineering approach is to maximize utilization of existing designs in order to minimize development of new technologies Minimize project exposure to technical and programmatic risks Ensure project schedule and budget are attainable Out of environmental and cultural respect, a strong desire to preserve the external appearance of CFHT after MSE completion MSE will reuse the CFHT summit building without additional ground disturbances Limiting size increase of the new facility building and enclosure to 10% CFHT MSE

10 Standing on the Shoulder of Giants Examples of existing designs and technologies are being utilized Segmented mirror system technologies from extra large telescope projects - TMT and ESO ELT Tilting spine fiber positioner and metrology technologies FMOS and 4MOST Spectrograph designs Hector and HERMES Commercial off-the-shelf high numerical aperture optical fiber No microlens optics No connectors to maximize system throughput, stability and repeatability CFHT summit facility

CFHT summit facility

12 Design Choice - OBF Reusing CFHT Observatory Building Facilities After seismic upgrade Reconfigure building layout to optimize workflow CFHT MSE

13 Design Choice ENCL Calotte style enclosure is selected after reviewing the trade study findings from the Thirty Meter Telescope project. Unique engineering solution with mass and geometry compatible with the existing enclosure pier Spherical form of the Calotte geometry is structurally more efficient than conventional enclosure configurations for the same size telescope Resulting in a lighter enclosure with lower construction and operation costs When used with CFHT s style vent modules, the Calotte geometry facilitates good ventilation to minimize thermal-inducted seeing.

14 Design Choice TEL Telescope optical design is driven by key SRD requirements such as sensitivities and field of view. The international design team developed four representative optical configurations, including WFC and ADC, for comparative study. The study was a detailed system level comparison of optical performance and non-optical attributes of the four designs.

15 Design Choice TEL Telescope optical design is driven by key SRD requirements such as sensitivities and field of view. The international design team developed four representative optical configurations, including WFC and ADC, for comparative study. The study was a detailed system level comparison of optical performance and non-optical attributes of the four designs. By comparison, the non-pf designs incur higher cost due extra mirror segments, additional M2 & M3, with little gain sensitive. After analysis of the four optical configurations m prime-focus telescope configuration was adopted. It represents the optimal design solution in terms of cost and optical feasibility. The adopted telescope optical design was reviewed and endorsed by external review panel in Feb 2016.

19 PosS Down-Select Three competing designs from AAO (Australia), USTC (China) and UAM (Spain) were evaluated. Design requirements: Positioners: >3,200 LMR fibres and >1,000 HR fibres Both fibre types must have full-field coverage System accuracy: 5 um (goal) Metrology camera system to provide closed-loop positional feedback Accuracy to be demonstrate by lab testing in Conceptual Design Phase

High target allocation efficiency Additional observing efficiency is enabled by simultaneous observation of both LR or MR, and HR targets System configuration time in <2 minutes for positioners System accuracy of 6 um RMS AAO test demonstrated FRD variations due to tilt <2% PO verified injection efficiency loss due to fiber tilt are insignificant in context of overall system sensitivity Design Choice AAO Sphinx
