| ASKAP Highlights - Production line of Mk II Phased Array Feeds |
| by Ant Schinckel (CASS) and the ASKAP team |
| While ASKAP commissioning continues at the
Murchison Radio Observatory with six Mk I Phased Array Feed (PAF) receivers,
back at the CSIRO workshop in Sydney pre-production of the first eight Mk II PAF
systems is well underway; three PAFs in different stages of assembly
are shown in the image above. Each PAFs consists of 94 "dominoes" for 188
dual-polarisation chequerboard elements, which are used to create 36 beams,
imaging a field-of-view of 30 square degrees in the sky. The PAF design process has taken advantage of the long history of engineering expertise at the ATNF supplemented by external skills through industry partnerships.
