Technology Development Project • NSF-funded 2007 -2011 for $12 M » Includes US contribution to the SPDO • Complementary to and integrated with Prep. SKA » EC-funded project 3+1 years, ~ same time frame as TDP • Targets areas that bear strongly on cost and basic performance (Ae, Tsys, B, cross polarization, processing) • Will deliver to the SKA project: 22 May 2008 » Technology options for LNSD array with broadband single-pixel feeds » Costing of reflectors+mounts vs. D and fmax » Optical designs that include both SP + PAF options (decision tree) » An SKA-optimized antenna, outfitted with feeds/receivers » Calibration and processing technology for LNSD arrays » Cost-modeling information for Meeting Washington, DC project decisions Jim Cordes US SKA Consortium
