No open AI identified

2) Update on NAASC & NA ALMA Ops activities (Hibbard)

  • Carol Lonsdale has accepted the position of NAASC Head, replacing Chris Carilli effective October 1 2008.
  • We have one offer out for the second CSV-liaison position. Other recent job actions are detailed in last meetings minutes.
  • The Canadian MOU is ready for signatures.
  • We will be writing the FY08 Program Summary and FY09 Progress Report in the coming weeks. These will be distributed to the ANASAC prior to your face-to-face meeting.
  • Because of the election, it is likely that we will go into FY09 under a continuing resolution. This means that instead of the anticipated budget of $11.8M, we may be funded at the FY08 rate of $7.6M. Considering carryover from FY08 (due to slower ramp-up of Chilean Operations), we expect that we will be able to operate throughout the first three quarters of FY09 (i.e. Oct08-Jun09) with relatively little impact (main impact: delay archive set-up, delay some hirings, delay any tutorials, science workshops and face-to-face meetings). The real pain comes in the final quarter. Since we have not yet received a bottoms-up estimate from Chilean Operations for CY09 and it comprises 60% of the FY09 budget (90% of the CR budget), it is pre-mature to worry too much about this now. We expect a revised Chilean Ops budget by mid September.
  • CASA
  • Splatalogue
  • ObsTool external test recently completed. 8 testers from NRAO/NAm ALMA participated.

3) Update on ALMA construction by NA project scientist (Wootten)

  • Status Report VertexRSI2 moved from SEF Assembly Building to an SEF antenna station by ALMA Transporter
Nine ALMA antennas are now on-site in Chile: four antennas from Mitsubishi Electric Co. (Melco) and five antennas from VertexRSI. These antennas are undergoing acceptance testing, after which they will leave the contractor’s camp for further tests at the OSF TB, including radiometric tests using the first ALMA receiver suite. These receivers are contained within the ALMA Front End, the first of which was successfully tested at the OSF in June. Recent successful tests at the OSF featured a system that included ALMA elements from the Front End to the correlator and the software interconnecting these devices. The massive antennas are moved by one of the two ALMA transporters; these achieved Provisional Acceptance and has moved the second assembled Vertex RSI antenna from the capacious (but with four antennas under construction, full) Site Erection Facility Assembly Building to an outside pad for holographic surface measurements. Later, a Melco antenna will be moved to the 16,400-foot elevation Array Operations Site (AOS) for high-altitude tests. Work is being completed on pad number 93, close to the AOS technical building, so that these tests may be efficiently accommodated.
  • ASAC Matters.
    • Face-to-face meeting in Charlottesville (Strawman Agenda) after Massive Star Formation Workshop
    • New Charges will require some work
  • Band 10 (350 micron) receivers accepted by ALMA Board as NAOJ contribution.
  • Commissioning and Science Verification
    • Rainer Mauersberger and Robert Lucas will be starting work in Chile in the next few weeks.
    • NAOJ has appointed Dr. Tsuyoshi Sawada as ALMA Commissioning Scientist; he will probably arrive in Chile in October of this year.
    • Dr. Stuartt Corder has accepted a Jansky Postdoc; he will spend two years in Chile working with the Commissioning Team before moving to Charlottesville for the science portion of his appointment.

4) ANASAC Face-to-Face meeting (Baker)

  • Friday September 12 at the NAASC in Charlottesville.
  • Charges: arrange subcommittees -- see Supplemental Material
  • Agenda -- See Supplemental Material

5) ALMA Workshops (Baker/Indebetouw)

2008, Sept 25-27 in Charlottesville. Registration is closed. We anticipate at least 120 participants. Science program available at

Workshop 2009: Evans will lead organization for workshop relating to "Star Formation and Accretion: Bridging the Gap Between Low and High Redshift". We have identified volunteers for a nascent SOC (Blain, Carilli, Heckman, Jogee, Prochaska, Wilson).

ANASAC Charges for Sept 12, 2008 Face to Face

  • Charge 1. The ANASAC has a standing charge to review the latest ASAC charges, and provide input to the ASAC members. We ask that the ANASAC pay particular to attention to the charge in which the JAO is asking the ASAC to take a prominent role in defining the scientific priorities for the ALMA development plan. Please discuss and recommend how the ANASAC can facilitate a mechanism to solicit the inputs and interests of the North American community and make sure the ASAC deliberations encompass the needs of the NA community.

  • Charge 2. Please organize the NAASC science workshop for 2009.

  • Charge 3. Continuation of interim charge II from January: "The NRAO asks the ANASAC to consider the issue of stimulating research in preparation for the use of ALMA, e.g., wide-field surveys to identify interesting targets, laboratory work on astro-chemistry, or theoretical work on star and galaxy formation, and how such preparatory research before ALMA is operational can be funded, as well as recommending avenues by which the NRAO or other organizations could promote such efforts." In light of the recent suggestion from the NSF/AST Division to convene a dedicated panel to review PI proposals on ALMA-preparatory work, we would like to separate this charge into 2 parts:
    • 3A. Finalize the current ANASAC response to the charge: "The NRAO asks the ANASAC to consider the issue of stimulating research in preparation for the use of ALMA, e.g., wide-field surveys to identify interesting targets, laboratory work on astro-chemistry, or theoretical work on star and galaxy formation, etc."
    • 3B. In the context of the recent NSF/AST suggestion of dealing with ALMA-preparatory PI proposals, consider potential ways to inform the community and to stimulate the submission of ALMA-preparatory proposals in the upcoming round of NSF/AST call for PI Proposals in November 2008. Also consider whether this suggested approach would be a reasonable long-term method of instituting an ALMA User Grants program.

  • Charge 4: The NRAO asks the ANASAC for considerations and suggestions on the potential use of the NA ALMA prototype antenna, once activities at the ATF terminate in Q3 2008. Three options have been proposed to date:
    • A) Incorporate into the ALMA array: This is possible, but not easy. The antenna cannot be transported with the transporter nor can it sit on a standard foundation. It would in effect be a fixed antenna that must be maintained in situ at the high site, and hence be expensive to maintain. Likewise, it would require a major (costly) retrofit, on top of the cost of taking it apart, transporting, and reassembling in Chile.
    • B) Sell it, and recycle the money back to ALMA, if a buyer can be found.
    • C) Use it for ALMA-related science, ie. give it away to an institution that can ensure good science comes out, with access by all of the NA community. The two mm/submm arrays come to mind, but it is also a superb single dish and, on a superb sight, could do interesting science as well. The question is: how to be transparent and fair in deciding who gets it? The cost of transport and reassembly would be the responsibility of the receiving party.
