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

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
  RD 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
