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.
First absorption line for ASKAP December 2013: CSIRO's ASKAP commissioning team has achieved a new science demonstration with the first HI absorption line measured with ASKAP antennas at the Murchison Radio-astronomy Observatory (MRO) in Western Australia.
Supercomputer launches toward Big Data November 2013: Today marks the official operational launch of the iVEC Pawsey Centre – a significant portion of which will be dedicated to processing radio-astronomy data from major facilities, including CSIRO's ASKAP telescope.
