CSIRO operated the Fleurs field station
from 1954 to 1963, when it was tranferred to the University of Sydney.
The
Chris Cross was completed in 1957
and comprised two arms of 32 parabolic 5.8-m diameter dishes.
The Chris Cross was complemented with the addition of an 18-m
(60-foot) prefabricated dish at the eastern end of the E-W arm.
Built by the firm of D.S. Kennedy in Massachusetts, the
"Kennedy" 60-foot (18-m) antenna was used in combination with the
dishes of the E-W arm of the Chris Cross to form the
Fleurs Compound Interferomenter
that could be used at night for non-solar radio
astronomy. Operating at 1420 MHz, and with a 1.5 arc-minute fan beam,
this new array was used for a high-resolution survey of selected
southern sources.
The Kennedy antenna was inaugurated on this day in 1961.
