After a couple of weeks of wet and occasionally wild weather, there
were many sighs of relief when Wednesday dawned sunny and calm,
as the cryoPAF (cryogenically cooled Phased Array Feed)
was scheduled to be have a test installation in the focus cabin
of the Parkes 64m telescope, Murriyang.
Installations proceed by tipping the Dish over, and hoisting the
receiver to a position above the top of the focus cabin. The Dish
is then stowed (pointing straight up) and the receiver lower
through the top of the focus cabin into position.
The cable to the right of the receiver is held on the ground to
ensure the receiver does not swing like a pendulum on its way up!
This test installation will last about 10 days, and allow some
on-dish testing of the cryoPAF performance. Final installation
is schedueld for next April. (Image credit: John Sarkissian)
