The Australian SKA Pathfinder - precursor to SKA1 Survey

June 13

12:10PM, Room 230, NRAO, Edgemont Road


The Australian Square Kilometer Array Pathfinder (ASKAP) will be the fastest cm-wave survey instrument in radio astronomy. ASKAP, a $188 million facility, will consist of 36 12-meter 3-axis steerable antennas, each with a large 192 element chequerboard phased array feed (PAF) operating from 0.7 to 1.8 GHz, and digital beamformer preceding the correlator. The phased array feed receiver system on each antenna will provide the first ever major "radio camera", with a 30 square degree field-of-view, allowing rapid, deep spectral and continuum surveys of the entire visible sky. The large data-rates involved (~ 100 Tb/sec) require a massive fibre based data transmission system followed by a powerful custom supercomputer (correlator).

The current status of ASKAP will be presented, as well as recent results from the Mk I PAFs. A brief update on the current design and status of SKA1 Survey instrument will also be presented.
