Practical solutions for realising an RFI compliant building for the Australian SKA Pathfinder telescope

The recently completed control building for the Australian SKA Pathfinder telescope at the Murchison Radio-astronomy Observatory (MRO) is a unique facility with a primary function of protecting the radio quiet environment at the remote MRO site. The building utilises inner and outer shielded chambers to attenuate RFI emissions generated by the beamformers, digital processing equipment and electrical plant. A geo-exchange cooling system supplies chilled water to the electronic processing equipment through RF filtered pipes.
