The
Lovell Multi-Beam Receiver
A
new four-beam receiver, shown in left, can now be installed
on the Lovell Telescope for use in hydrogen line and pulsar
surveys. Each beam receives signals from a slightly different
region of the sky. The whole receiver can be rotated so that,
by aligning the feeds appropriately, they can observe four parallel
strips of the sky for each scan of the telescope. It is equivalent
to building three new 76-metre telescopes but at a fraction
of the cost!
The
University of Wales H-Line Survey
The multi-beam receiver is being used by astronomers at Cardiff
to carry out a very sensitive hydrogen line survey of the northern
sky. A test observation is shown left.
