Took place on 5 October 2012 at the MRO for 195 guests (+18 media representatives + 27 support staff and 47 contractors). A total of 289 people onsite. Distinguished guests included:
Minister for Tertiary Education, Skills, Science and Research Senator the Hon. Chris Evans; Minister
for Science and Innovation Hon. John Day MLA; Minister for Human Services, Senator the Hon. Kim Carr
; Senator for Western Australia, Senator Louise Pratt; City of Greater Gealdton, Mayor Ian Carpenter, members of the SKA and CSIRO Boards, Ambassadors of SKA Member countries and Wajarri Yamatji community leaders. Guests were transported by plane or bus to the MRO site, served morning tea on arrival, joined an official opening ceremony and served lunch before departing.Local events also took place at CSIRO’s Marsfield, Parkes, Narrabri and Tidbinbilla sites for 200 CASS staff.

Included in the Official Opening Ceremony of the ASKAP and MRO was a Naming Ceremony for 30 ASKAP antennas. (The first six antennas were named in an event held in June 2011.)
All 36 antennas now have
Wajarri-Yamatji names. The names are a collection of Wajarri family names as well as words from the
Wajarri language for native flora and fauna and landmarkings around the MRO, objects in the sky and Wajarri dancing.ASKAP Antenna Naming CeremonyImage credit: Dragonfly Media

Within the current ASKAP budget scope is the installation of six first generation state-of-the-art phased-array feed (PAF) receiver (MkI) systems and twelve second generation (MkII) systems to be installed on 18 ASKAP antennas. The six MkI PAF systems will form the ASKAP BETA array. The twelve MkII PAF systems are being developed under the ASKAP Design Enhancement Program (ADE). CSIRO is currently seeking additional capital funds to outfit the remaining 18 ASKAP antennas with the same MkII PAF systems.
The transition from ASKAP construction phase to ASKAP operations phase, as part of the Australia Telescope National Facility, is underway
and is following the timeline for transition from BETA engineering commissioning to BETA science commissioning. This transition is expected to be complete by end 2013.The build-out of the additional PAFs will continue once ASKAP BETA is operational.
Antenna+PAF systems will be continually absorbed by ASKAP operations. ASKAP Project Status Summary

36-dish ASKAP with 12 PAFS
Complete
36 antennas
A minimum of 12
antennas
equipped with Phased Array Feed (PAF) receivers, 6
of which are new generation Mark II PAFs
Remaining antennas fitted with single pixel feed technology
Meaningful
astronomical science is undertaken at this stage.
Dec 2013

The fourth BETA MkI PAF arrived at the MRO in September 2012 and is currently being installed on one of the ASKAP antennas. Progress
continued in Marsfield on the next two PAFs (BETA PAFs #2 and #3)
.There are just ten weeks to go until the Integration Readiness Review for the ASKAP Design Enhancement Project (ADE). This will be an internal review.
The latest revisions to the ADE LNA have reduced the minimum noise temperature from 35K to 27K. Characterisation of the MkI PAF installed on the 12-m Parkes Testbed Facility continues. PAF Development
Figure 1 shows for the first time an estimate of the point source sensitivity across the full field-of-view (FoV) of the PAF. The image combines the response from 36 single-polarization formed beams on a 6x6 square grid with 1 degree spacing. Each beam is approximately 1 degree half power beam width (FWHM), using 1 MHz bandwidth at 1312 MHz.

Verification tests of the three-PAF BETA 1 system commenced in June 2012. In August 2012, the three-PAF BETA 1 system produced ‘first fringes’ as well as demonstrated phase closure.
A flawless live demonstration of the three-PAF BETA-1 system took place during the ASKAP Opening Ceremony. An internal review of BETA delivery took place on 19 October 2012 that included presentations on the current and planned capabilities of the BETA system. A summary of this review will be forthcoming.

The current three-PAF BETA 1 system utilises a software correlator that uses 'raw data capture' from memory on
beamformer cards. The associated hardware is capable of handling data from
16 bands, each 1 MHz, spanning 300 MHz bandwidth and a 1:10 duty cycle (i.e. it takes 10 seconds to download 1 sec of data). The hardware limits the number of beams to maximum of 4. With the current computer setup reliable correlation for 3 beams is possible (with a soon-to-be installed dedicated machine this will increase to 4 beams).
Will implement an expansion of the software correlator capability to 15 baselines and up to 9 beams for the same 16 MHz bandwidth and 1:10 duty cycle prior to the hardware correlator coming online. A period of simultaneous use will follow.ASKAP Software Correlator

Based on feedback from the ASKAP Survey Science Teams, new ASKAP Project Scientist Lisa Harvey-Smith reviewed membership, scope and leadership of the ASKAP Working Groups.
A draft of the ASKAP Publications Policy has been developed and was reviewed by ASKAP Survey Science Teams at their meeting held on 11 September 2012. The ASKAP publication policy applies to the publication of all measurements or images derived from ASKAP, including sub-arrays (e.g. BETA or any other stage of ASKAP development) and the full ASKAP system. It also applies to technical descriptions relating to any element, sub-system or system of ASKAP. This policy also applies in situations where third-party hardware, software or firmware is installed on ASKAP.
A PAF Applications Workshop was held on 22 October 2012 with staff from CASS and the ICT Centre.

Practical completion of the MRO site infrastructure work occurred on 29 June 2012 and the MRO control building and all infrastructure have been handed over to CSIRO.
The MRO-Perth Fibre Link is up and running and currently being used at the
2 Gb/sec level. On 10 August 2012 the MRO control building was connected to the MRO-Geraldton fibre network and the planned 40 Gb/s connectivity is expected in December 2012.
Murchison Radio Observatory (MRO) Site and Supporting InfrastructureOf the required MRO Infrastructure only the power station remains to be installed. As planned, the MRO is now operating from a rental diesel generator pending completion of proposed Horizon Power Stage 1 power system (2014).

MRO Support Facility (Geraldton)
The build of the
MRO Support Facility (MSF) located at the Geraldton Universities Centre is on track and scheduled for occupancy in early 2013.

Director’s response to ATUC Report – July 2012
ATUC recommendation
Director’s Response
The ATUC encourages the ASKAP team to focus on a science application that can demonstrate the power of the PAF design. There should be a track to early publication of results as soon as possible.We are working with the science survey teams through ASKAP WG4b to solicit short test observations that will both verify the performance of the PAFs as well as showcase the technical niche that PAFs occupy.We are also working through test fields observed with the ATCA to produce high dynamic-range images of large complex fields near Fornax and Circinus. These will provide an early demonstration platform for ASKAP's PAFs.
We are committed to speedy publication of the results.Slide19
