Title: Transition from SKADS to PrepSKA


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

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
    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
