  1. Transition from SKADS to PrepSKA Richard Schilizzi Lisbon, 3 October 2008

  2. PrepSKA deliverables • Produce a deployment plan for the full SKA and a detailed costed system design for Phase 1 • Integrate all of the activities, reports, and outputs of the various working groups to form an SKA implementation plan including a build plan proposal for construction funding in 2012

  3. PrepSKA Work Program WP1 PrepSKA management WP2 Costed telescope design WP3 Further site characterization in Australia and Southern Africa WP4 Governance WP5 Procurement and involvement of industry WP6 Options for funding WP7 Impact on broad government priorities

  4. PrepSKA

  5. EC-FP7: PrepSKA System design Funding Governance Site Selection SKA timeline SKA-mid+low Complete Site Select Reference Design selected SKA Pathfinders Complete Phase 1 complete Preliminary SKA specs External Engineering Review of design Sites short-listed Pathfinder science Full science operations SKA mid+low Early Science SKA mid+low 06|08 | 10 | 12 |14 | 16 | 18 | 20 | 22 | 24 | Concept Design System Design Detailed Design/Phase 1 construction and commissioning SKA mid + low construction and commissioning Design Studies /Pathfinder Suite Construction Concept design for SKA-high System design SKA-hi SKA-high Construction

  6. WP2 deliverables(Peter Dewdney “Guiding Principles, Activities and Targets for WP2”) • Technology selection • System Design • including operational – construction tradeoffs • Science Performance vs Reference Science Mission • Total cost estimate for Baseline Design (incl. contingency) • Risk assessment • Design and deployment plan • Top-level build schedule • Upgrade paths

  7. The Job of WP2 Science Requirements Case Studies Eng. Simulations Four Years Prototypes Pathfinders Technical R&D SKACost Readiness Assessments Engineering Design & Cost National PrepSKA SKADS TDP LOFAR ASKAP KAT7 ATA EVLA MWA eMERLIN eEVN Path2SKA

  8. Approach • Focus WP2 Description of Work in a different way • Move from 40 technology development tasks, including an ill-defined ‘IVS’ to assembly and verification of large SKA sub-systems • identify and fill gaps Note: Need an integrated systems approach at sub-unit level, eg • Feed dish design; LNA feed design • Dish Verification Program • PAF Verification Program • AA Verification Program • Signal transport Verification Program • …..

  9. Original WP2 technology matrix

  10. Dish Verification Program

  11. WP2 approach • Required parameter space can be covered with a small no. of models • Contributing institutions contribute designs to several models • Verification Programs will need to include a build and test phase, on the way to deriving the cost by 2012Q1 (end of PrepSKA) • VPs are self-evaluating • SKA Design Studies and Pathfinders provide the R&D basis for the VPs • Need to target those aspects that map into the SKA • Documentation essential • Effectively evaluate the feasibility of implementations outlined in Memo 100

  12. Representative implementations: Phase 1

  13. Representative implementations: Phase 2

  14. SPDO in the PrepSKA era

  15. SPDO Engineering Team Project Engineer Peter Dewdney System Engineer Kobus Cloete Domain Specialist Receptors Neil Roddis Domain Specialist Signal Transport Roshene McCool Domain Specialist Computing & Duncan Hall Software Domain Specialist Signal Processing advertised Site Engineer Rob Millenaar Project Management Officer interviews next week

  16. Liaison Engineers Senior engineering managers Roles • Lead design teams for which the Lead Institution has assumed responsibility • Serve as communication person for relations between SPDO and Lead Institution

  17. WP2 Schedule • SPDO staffing, familiarisation and training (ongoing) • Appoint liaison engineers (ongoing) • WP2 Kickoff meeting, 10-14 Nov (Deliverable #1) • MoAs with organisations/lead institutions (ongoing) • Review Reference Science Mission, Dec08 • State of SKA technology • call for documentation (Jan 09) • Review by International Engineering Advisory Committee, Mar 09 (Deliverable #2)
