David Mullen, project engineer at Aavid Thermacore Europe, said: "CSIRO approached our Australian distributor, JHC Specialised Solutions, to explore the possibility of using Aavid Thermacore's technology in the ASKAP project almost four years ago.
2-metre diameter complex assemblies with embedded heat-pipes, thermoelectric fin-stack coolers, and heat transfer assemblies to CSIRO in Sydney, who then integrated them into the PAF receivers and dispatched them to ASKAP engineers on-site in Western Australia.
With all these new-and-improved features to play with, ASKAP astronomers hope to reveal more about the evolution of the universe, how galaxies are formed, and the role of magnetic fields in galaxies (including our own).
According to Wicenec, ASKAP produces some 250 terabytes per day of raw data, more than 15 times the nightly data forecast for the upcoming Large Synoptic Survey Telescope (S&T: Sept.
But contrary to MeerKAT, ASKAP will not become part of the SKA: SKA-low will be at the same site, but it will use a completely different kind of antenna.
Dr Duffy said two ASKAP surveys, WALLABY and DINGO, would examine galaxies to study hydrogen gas - the fuel that forms stars - and how those galaxies had changed in the last 4 billion years, allowing us to better understand how our own galaxy, the Milky Way, grew.
Dr Duffy said the new ASKAP galaxy surveys would also allow astronomers to probe the nature of one of astronomy's greatest mysteries - Dark Energy.
And Prof Womersley told BBC News: "The important aspect of doing it this way is that we will get more science out of the project in the first phase by taking advantage of the existing ASKAP and Meerkat investments.
These ASKAP results are generating great excitement in the office of the SKA Organisation in Manchester, UK, and at an SKA science meeting currently taking place in Italy, because they clearly demonstrate the revolutionary potential of CSIRO's new phased array feed technology," Dr Ball said.
ASKAP, one of two precursor telescopes at the remote site in the Mid-West Region of WA, is developing and proving ground-breaking Australian technology which will eventually be incorporated into the SKA.
Using the Dutch APERTIF, the Australian ASKAP and the South African MeerKAT SKA precursor telescopes (this project has already been allocated 8 months of observing time on the latter), we will directly observe the presence and establish the importance of accretion.
The State Government s investment will ensure the site is ready for the SKA and coincides perfectly with CSIRO s aim to switch on the first six ASKAP antennas later this year.
