  1. TDP Activity Report Lynn Baker US SKA Consortia Meeting Madison, Wisconsin November 17, 2008 Lynn Baker US SKA Consortia Meeting Madison WI

  2. TDP Related Papers At The URSI Meeting Chicago, Ill. August 12-15, 2008 • Overall TDP report, many authors, presented by Lynn Baker • Sandy Weinreb, LNA and quadridge feed results • German Cortes, QSC feed results • Athol Kemball, Jim Cordes, Jack Welch, related topics Lynn Baker US SKA Consortia Meeting Madison WI

  3. SKA Advisory Committee Meeting Washington DC September 10, 2008 • Jim Cordes, Athol Kemball, Lynn Baker representing the TDP • Advisory Committee mostly satisfied with TDP activities and planning • 11 committee recommendations, all being integrated into TDP plans and activities Lynn Baker US SKA Consortia Meeting Madison WI

  4. Work Package 2 Kickoff Meeting Manchester, England November 10-14, 2008 • TDP work block structures well aligned with SPDO work blocks • Concerns and differences on schedules and timelines • Parallel execution of work blocks presents decision making challenges • SPDO documents need to better reflect total TDP contributions Lynn Baker US SKA Consortia Meeting Madison WI

  5. TDP / DRAO Collaboration • DRAO developing high performance, cost effective composite reflectors • DRAO developing focal plane phased array feeds • TDP studying overall antenna designs but not working on PAF’s • Integrate DRAO results into TDP evaluation of antenna technology • Provide DRAO with subsystem information and design to support their efforts Lynn Baker US SKA Consortia Meeting Madison WI

  6. Mk2 Reflector with Phased Array Demonstrator feed attached. • Mk2 reflector has improved: • Surface accuracy • Stiffness • Manufacturability • Cost

  7. Patriot Antenna Systems Study Contract • Short (~6 month) study to provide costing of 2 exemplar antennas • Estimate costs as specifications of exemplars are changed • Study extension of antenna fabrication technology to lower costs • Study improved mounts for cost savings Lynn Baker US SKA Consortia Meeting Madison WI

  8. TDP Planned Measurement Facilities • Feed and LNA development requires accurate and consistent measurements • Noise measurement of feed/LNA combinations, based on cold sky technique, needs radio quiet location, possibly NRAO, Greenbank • Feed measurements require a good antenna range. Cost estimates of a range at Cornell will be compared with commercial options. Lynn Baker US SKA Consortia Meeting Madison WI
