ASKAP is designed to be a high speed survey instrument with high dynamic range. This requires an extremely wide field-of-view interferometer with Phased Array Feeds (PAFs). The PAF has a total of 188 elements, 94 in each of two polarizations.
The specification for ASKAP is:
A total collecting area of approximately 4,000 square metres, from 36 antennas each 12 metres in diameter
System temperature less than 50 K
Frequency range from 700 MHz to 1.8 GHz
300 MHz instantaneous bandwidth
36 independent beams, each of about 1 square degree, yield overlapping to a 30 square degree field-of-view at 1.4 GHz
Maximum baseline of approximately 6 km
Full cross-correlation of all antennas
Possible remote array station capability located in NSW, approximately 3,000 km from the core site.
Tackling the SKA engineering challenges of tomorrow November 2015: Representatives from CASS are this week joining over international 200 engineers at the second annual SKA Engineering Meeting, to consider the engineering challenges of the future mega-science project, the Square Kilometre Array (SKA) telescope.
Now available: 3TB ASKAP data for public discovery November 2015: An 'initial release' of ASKAP demonstration data has today been made available by the CSIRO ASKAP Data Science Archive (CASDA) team, as a vital step in preparation for the start of ASKAP Early Science in 2016.
First multibeam image for ASKAP's newest receivers November 2015: Early commissioning trials of four ASKAP antennas installed with the second generation (Mk II) phased array feed receivers have resulted in the first multi-beam image for the ASKAP team.
