Large Southern Array Project

Phase 2 Activities of European Large Southern Array Project

Funded under the International Collaboration Project of the
MNRF Program


Proposer: J Whiteoak

The Large Southern Array (LSA) is a European project involving the construction of a new-generation, Southern Hemisphere, millimetre-wave synthesis telescope. Present specifications call for a collecting area of 10,000 m2 and an angular resolution of 0.1 arcsec at 100 GHz. Both specifications are an order of magnitude improvement over those of existing mm-wave instruments and, with at least 50 antennas in the array, the large number of interferometer baselines will yield vastly better image quality. Developments since the LSA concept was first proposed make it likely that the European project will be merged with the US Millimeter Array (MMA) project, leading to a single millimetre and sub-millimetre array located in northern Chile. The MNRF contribution to the Phase 2 LSA Activities is to allow Australian scientists and engineers to contribute to LSA/MMA planning and design groups dealing with matters such as scientific goals, software, system design and calibration. These activities will ultimately facilitate Australian access to the new instrument, as well as lead to techniques contributing to more effective operation of the upgraded Australia Telescope Compact Array.
