Abstract :
The Australian SKA Pathfinder (ASKAP) is a new survey telescope, using phased-array feeds (PAFs) to provide a wide field of view, with 300MHz instantaneous bandwidth over the frequency range 0.7-1.8 GHz. ASKAP is currently under construction in outback Western Australia at the Murchison Radio-astronomy Observatory (MRO). ASKAP will consist of an array of thirty-six 12-metre diameter dishes, each equipped with a PAF with a `chequerboard´ planar feed structure to provide a field of view of 30 square degrees.
