[ASA] Funding for ASKAP PAFs and operations

[Yeshe Fenner]

Dear ASA members,

CSIRO
<http://www.csiro.au/Organisation-Structure/Divisions/Astronomy-and-Space-Sc
ience.aspx> and Astronomy Australia Ltd (AAL
<http://astronomyaustralia.org.au/> ) are pleased to announce that funding
has been secured to enable the Australian Square Kilometre Array Pathfinder
(ASKAP <http://www.atnf.csiro.au/projects/askap/index.html> ) to be equipped
with a total of 30 Mark II Phased Array Feeds (PAFs), six of which will be
installed on the central BETA antennas that are currently fitted with Mark I
PAFs. Installing Mark II PAFs on BETA antennas will introduce a number of
short baselines that will significantly enhance the surface brightness
sensitivity of the array, thus boosting surveys of neutral hydrogen emission
from the Milky Way and nearby galaxies.


This has been made possible through an agreement between AAL and CSIRO in
which AAL is allocating $6M for ASKAP early operations and CSIRO will
provide a matching contribution to construct, install and commission six
additional Mark II PAFs. This agreement brings the total number of funded
Mark II PAFs to 30, emphasising CSIRO's continued commitment to the success
of ASKAP. 

CSIRO intends to engage with the community regarding the order in which to
roll-out the Mark II PAFs numbers 13-30. The expected timeline for community
consultation and deployment is given below:

*	21st October 2014: All-day community workshop to discuss options for
the order in which ASKAP antennas are fitted with Mark II PAFs #13-30,
including when the BETA Mark I PAFs will be relocated from their locations
during commissioning (further details of the workshop will follow).

*	April 2015: Roll-out plan for ASKAP Mark II PAFs #13-30 is
finalised, taking into account community input.

*	By mid-2018: Installation of 30 Mark II PAFs, including six on the
central antennas, is completed.


CSIRO and AAL thank the Commonwealth government for its support of ASKAP
through the National Collaborative Research Infrastructure Strategy (NCRIS)
and the Collaborative Research Infrastructure Scheme (CRIS) programs.

Kind regards,

   Lewis Ball, Chief, CSIRO Astronomy and Space Science 

   Mark McAuley, CEO, Astronomy Australia Ltd
