US Technology Development for the Square Kilometer Array The Large-N/Small-D Concept

The SKA2004 Penticton project emphasizes technology development for the Square Kilometer Array (SKA), aiming to enhance U.S. involvement in this international initiative. Coordinated by the SKA Consortium, led by Yervant Terzian and Jack Welch, the project focuses on antenna optimization, low-cost manufacturing, and robust signal processing. With NSF support of $1.5M and key milestones outlined, the initiative aims to develop critical technologies while fostering education and public outreach, ensuring the SKA's success as a leading astronomical project.

  3. US NSF Support • Current NSF Support: 3 yr/$1.5M grant from the Advanced Technology and Instrumentation program • TDP Proposal • Guidelines from the NSF June 2003 • Discussion and outline phaseJuly-Sept 2003 • Task identification and organizationOctober 2003 • Development of TDP Management Plan November 2003 (approved) • Identification of workplan, tasks,timeline, budgets, and writing Oct 2003 – Feb2004 • Submitted to the NSF March 2004 • Reverse site visit to the NSF October 2004 • Initial funding 2005.0 (?) SKA2004 Penticton

  4. The US SKA Consortium’s Technology Development Project Overarching goal: develop the LNSD concept so that it will be an integral part of the international SKA project. • End-to-end design concept • Costing consistent with anticipated budget ceiling • Timeline and milestones consistent with the overall project timeline set by the International SKA Project • Significant Education and Public Outreach Component SKA2004 Penticton

  5. The US SKA Consortium’s Technology Development Project Technical aspects of the TDP: • Optimize antenna/receiver design • Develop manufacturing process for low-cost antennas • Define and develop plausible plan for wideband signal transport and digital processing • RFI mitigation and management • Post processing for large FOV surveys (innovations in high performance computing, networking; IVO) • Operations and maintenance plan • Costs and trades SKA2004 Penticton

  6. 5-year Technology Development Project 7 main work areas (“Subprojects”) • Antennas and receivers • Signal transport and digital processing • Systems analysis and design • Construction and Operations costing • The ATA as a development facility for SKA feeds, receivers, RFI, large-N ops • Siting the SKA in the US • Education and Public Outreach SKA2004 Penticton
