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.
Highlights and achievements of 2014 December 2014: What a year it has been for ASKAP, with many highlights throughout the year in early science and commissioning, significant advancement of ASKAP technological development, and progress in SKA pre-construction R&D activities.
ASKAP wins national innovation award November 2014: ASKAP has taken home the overall prize in the Australian Innovation Challenge Awards, with judges recognising the telescope as “one of those advances that keeps Australia on the global innovation map”.
