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

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

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 • …..
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
