UTMOST-2D

We are currently in the process of upgrading the North-South arm of the Molonglo telescope to similar or sensitivity as the operational East-West arm, using technology designed on site and at Swinburne University of technology.

The project is a major part of a Future Fellowship, awarded by the Australia Research Council, to Dr Adam Deller at Swinburne.

Combined with the East-West arm, UTMOST-2D will lead to localisation of the origin of Fast Radio Bursts to a few arcseconds on the sky, sufficient to identify the host galaxy from which they came.

Removal of the defunct modules on the North-South arm, so that legacy electronics can be stripped and refitting done with the new antennas, LNA (Low Noise Amplifiers) and beamformer boards can be carried out.

UTMOST-2D antenna and Low Noise Amplifier (LNA) coupling for use on the North-South arm upgrade. The dual-pole design brings about 10 times the sesnitivity of the receivers on the East -West arm.
