SKA update Sarah Pearce| Deputy Director, CSIRO Astronomy and Space Science November 2016 CSIRO ASTRONOMY AND SPACE SCIENCE

3 sites - 2 telescopes; HQ 1 Observatory Project scope Phase 1 Construction: 2018 – 2023 Construction cost: ~€800M (?) Operations cost: ~€130M/yr, TBD

Australian pre-construction roles Consortium Australian partners Assembly Integration and Verification CSIRO Central Signal Processor CSIRO, Swinburne University of Technology, CISCO Australia Dish CSIRO (consortium lead), RPC technologies Infrastructure Australia Aurecon, CSIRO (consortium lead), Horizon Power, Radio Quiet Zone (RQZ) Solutions Rider Levett Bucknall Low Frequency Aperture Array ICRAR, MWA, CSIRO Science Data Processor ICRAR, CSIRO, iVEC Signal and Data Transport AARNet, CSIRO, UWA Telescope Manager

CASS in SKA1-Low pre-construction Leading Australian Infrastructure consortium Engineering work by Aurecon Leading correlator and beamformer for SKA1-Low With Astron and AUT Australian lead for Assembly, Integration and Verification Imaging and calibration in Science Data Processor Contribute to Signal and Data Transport, Telescope Manager Recently invited to join Low Frequency Aperture Array on behalf of MWA Many other Australian organisations also working on SKA1-Low, including ICRAR (Curtin and UWA), AARNet, Swinburne, industry partners The ATNF in 2017 and beyond

AAVS and EDA WWW.SKA.GOV.AU ICRAR leading deployment of AAVS Antenna bases for the Array Verification System (AAVS1) are being put into position in anticipation of antennas being deployed late 2016 Initial implementation of the Engineering Development Array (EDA) is complete EDA is a dedicated test and verification platform for further development of MWA and commissioning of AAVS1 It is currently being used to verify the performance of the system developed to facilitate ingest of signals from ‘external instruments’ into the MWA signal chain.

Status of Design activities All 9 consortia have completed Preliminary Design Reviews Massive effort – 100s documents Some issues, as expected, but closing off now Detailed design moving to Stage 2; System Review Q1 2016 System PDR end 2016 Critical Design Reviews 2017 – 2018 DIIS funding ran until end 2016. Extension funding from NISA – call for proposals expected before Christmas

Inter-governmental Organisation SKA Member governments are negotiating the establishment of an intergovernmental organisation (IGO), similar to ESO/CERN/ITER/ESA. Will provide: Long-term government commitment and funding stability Availability of Privileges and Immunities from members ‘Freedom to operate’, specifically through procurement process NISA announcement of $293.7m for SKA: needs Cabinet approval for release Includes funding for: SKA construction SKA operations up to 2026 ILUA Site Entity Pre-construction extension

IGO: formal negotiations Rome: 14-16 October; 26–28 January; 19-21 April; 27-29 Sept; Minister Vicente (Italy) – Chair. All 10 countries present Canada observer Germany recently joined negotiations as observer Issues remaining include: Weighted voting IP policy Procurement model Aiming for approved text in Feb Ministerial signing mid-2017

Construction SKA construction will be mix of cash and in-kind procurement ‘Fair work return’ will ensure return to Australia CSIRO main areas of interest: Integration and commissioning Digital signal processing for SKA1_Low Managing infrastructure construction Computing - calibration and imaging

Engineering development SKAO will have an Observatory Development Programme Co-funded engineering activities from member countries Four areas identified Phased Array Feeds SKA1_Low development Mid-frequency Aperture Array Wide-band single pixel feeds Aim to lead PAF activity Setting up PAF consortium in pre-construction Likely partners Italy, UK, Netherlands, China, Germany, Sweden

Site Entity Responsible for Australian deliverables: Radio quiet Indigenous Land Use Agreement (ILUA) – new ILUA “Landlord” of the site – holds the lease, agrees other users Manage shared facilities – eg roads, fibre etc. ILUA negotiations have started Working with WA Gov and DIIS on lease and agreements

SKA Operator Manages ‘on site’ activities for SKA Includes routine maintenance, hardware engineering, aspects of software engineering, and performing observations. CSIRO and SKA SA preferred contractors for this role Staff based in Geraldton – probably fly-in-fly-out

SKA Observatory Office in Australia Staff based in Australia but employed by the international SKA Observatory Technical performance monitoring, calibration, aspects of science data production, QA, project support and aspects of software engineering. Intended to be based in Perth Manage interface with SKA Operator, Science Processing Facility (Pawsey Centre)

Science processing facility High performance computing centre - ingest data and produce and store data products. Under contract to SKA Observatory Fundamental part of the telescope for real-time processing Planned to be Pawsey Centre in Australia

SKA Regional Centres SKA Observatory will deliver data to archives in Perth and/or Cape Town. Members will establish SKA Regional Centres to help support SKA science. Loosely based on the CERN model of the Worldwide LHC Computing Grid Provide processing, storage, user support and others Peter Quinn leading Australian committee to plan Regional Centre Potential collaboration with NZ and China Critical part of CSIRO’s role in SKA Consult with community on your needs for the Australian SRC

Australian SKA Science Advisory Committee Chaired by Carole Jackson (ICRAR/Curtin) Stuart Wyithe Lister Staveley-Smith Lisa Harvey-Smith Naomi McClure-Griffiths Andrew Hopkins Simon Johnston Elaine Sadler SKA Fellowships Four Fellows approved: Natasha Hurley-Walker, Martin Meyer, Warren Bax, Attila Popping Work for ~3 months at SKA HQ in UK Briefing community afterwards – probably at OzSKA

CSIRO SKA Staffing Warren Bax – 4 month secondment to SKA HQ – finance for the IGO Ant Schinckel – 75% secondment to SKA HQ on Operations Planning for SKA1_Low Mainly still based in Australia Ramp up as ASKAP-30 construction comes to an end Kate Chow maternity leave – Howard D’Costa SKA Information Officer recruitment Phil Edwards – SKA Project Scientist Working with and on behalf of the Australian astronomy community Acting as point of contact for the Australian science community on SKA science matters Keep the science community updated with progress on SKA Helping to organise meetings, eg OzSKA, conference pre-briefings, and the SKA Fellows Programme Build a cohesive Australian SKA science community
