SKADS1WorkshopAvA Coordinators report SKADS Square Kilometre Array Design Study implemented as Specific Support Action A Cohering Program toward mid-2009 With 29 partners from 8 EU countries plus S.A.,Canada and Australia and collaborations to US and China “Nothing is so firmly believed as that we least know” Michele Montaingne ( )/cited IAUXXVIIthJournal Emphasizing Phased Arrays for Radio Astronomy in the next decade

SKADS1WorkshopAvA SKADS Main Objectives Total funding 38M€ program EC funding M€ Industry involved from the start to –Demonstrate SKA Scientific Viability and Readiness –Demonstrate cost-effective Engineering Solutions and Technological Readiness –Deliver a costed SKA Design Activity Scope Distribution of work (% of total) Organization & Management8 System level Aspects22 Tile Level Technologies30 Demonstrators30 Assessments and Integration Plan10

SKADS1WorkshopAvA Science and the Aperture Synthesis instrument for Radio Astronomy image Correlation Imaging Station 1 2N Baseline Baseline longer Resolution increased (VLBI: ~milliarcsec.) # stations higher Improved calibration & imaging Larger collecting area Increased sensitivity (In R.A. expressed as A eff /T sys ) Other aspects: Frequency bandwidth (span, instant.) Dynamic range (in image map) RFI Configuration, Site Steaming Data, Computing power, Archiving Network performance etc. Many inderdependencies! Configuration Resolution, imaging, brightness sensitivity etc.

SKADS1WorkshopAvA Design Studies 1 to8 Work has Clear objectives, Milestones and Deliverables to provide outcomes in measurable and verifiable form. DS1: Overall coordination and management. DS2-6: Activity Cores, sub- divided into 21 coherent Design Study Tasks (DSx-Ty) DS 7-8: “Synthesizing” the results from DS2-6 Structure optimized to continuously map the scientific requirements on the technical specifications to produce a common design goal

SKADS1WorkshopAvA SKADS scope: the entire SKA system Computing intensive Storage intensive Signal intensive Receiving and Collector Concept, Station-level Signal Conditioning and Processing Architecture Wide Area Data transport Network Control and monitor software Data reduction and Imaging Central Processing Distribution, Archiving and Use by astronomer Data intensive SKADS Foci: Blue = Technical R&D work Yellow= Assessment Studies Lightest Yellow= Least emphasized

SKADS1WorkshopAvA SKADS: Based on phased arrays Multiple f-o-v philosophy for flexibility and surveys Aperture Arrays “electronic fish-eye lens” Focal Plane Arrays “radio cameras”

SKADS1WorkshopAvA SKADS Activities First Year finishing and agreeing the DOW with all participants, successfully finishing the contract negations to the EC setting up the project management and control organization including the appointment of the project manager, scientist and engineer to start the project and line-up/synchronize the activities in all tasks according to the DOW to get agreement on the Consortium Agreement and the associated agreement on the Pre-Existing Know How. to properly set up the internal and external communication representation and documented reporting to set up webpages as project communication and progress tool to finish first Annual report Other activities: –to formalize closer connections from SKADS to the International SKA project recognizing that SKADS is the major endeavour on the SKA context –to increase the inflow of (new) scientific insights into SKADS –to absorb developments in the SKA context in as far as relevant to SKADS –to optimize the representation of other European countries and SKA (related) activities in the US and elsewhere

SKADS1WorkshopAvA Achievements so far Implementation of PM tools SKADS management complete SKADS Project Office complete All scientific and technical DS-activities started Recruitment process started First results dripping in, see Agenda Improved connection to ISPO & SKA Improved Science input through Science Advisory Group (“SAG”) Clear reference for SKADS through “SKADS Benchmark as Reference Design”
