May 2006 – NRAO Users Committee Meeting

NRAO, Socorro, New Mexico

ALMA Operations on 1 page (ProjPlan)• “The Joint ALMA Observatory (JAO) is primarily a service organization for

conducting the activities in Chile that are required to acquire, certify, and archive the scientific data for the User communities. The interface to ALMA for each of these communities is an ALMA regional center (ARC).”

• Array Operations Site (AOS), Chajnantor: ALMA array reconfiguration, site security, correlator – modular design to mitigate high-site maintenance

• Operations Support Facility (OSF), San Pedro: Operate array, select schedule blocks, ensure adequate calibration, quick-look data monitoring, Quality Assurance 0 (AoD), basic module repair, standard antenna maintenance, safety, administration

• Central Office (Santiago): Pipeline, QA1, Archive, Business, Science office

• ALMA regional Centers (ARCs), C’ville, ESO, Tokyo: Proposal functions, sched block preparation, basic user support and feedback, archive copy and research, QA2, module maintenance & repair, software M&R, OSF staffing (AoD), H/W + S/W development, advance science support and development

North American ALMA Science Center Organizational Chart



North American ARC: Science Div.

• Proposal and Scheduling Functions:• Review and evaluate the Proposal

Submission Tool (PST), and assist proposers

• Issue call for proposals• Organize review and ranking of NA

proposals• Provide assistance to users in

generating observe files • Verify and correct schedule blocks

• User Science Support:• Participate in Commissioning and

Science Verification• Review and evaluate the pipeline and

off-line data reduction software, cookbooks, and web pages

• Disseminate full uv data sets• OSF staffing: “Astronomer-on-Duty”• Quality assurance and user feedback

to OSF• Post-observation user support via

helpdesk

• Archive support:• Operate NA ALMA Archive (>100

Tbytes per year; cf HST 20 Tbytes total)

• Support archive research• Provide interface to the VO



• Hardware and Software Maintenance and Repair• Maintain and repair

hardware and software developed by NA during construction

• NA Software deliverables: Scheduling, real-time system, pipeline, correlator, offline.

• NA Hardware deliverables: Band 3, Band 6, Back End assembly, LO, IF & DTS system, correlator, antenna power supply.

ARC Technical and Software Divisions

• Hardware and Software Development• Develop algorithms and

software for new observing modes or new computing H/W

• Develop new pipeline heuristics

• New ALMA observing bands

• SIS fabrication

• mixer development

• Photonic LO

• Advanced WVRs …

Science/community driven: Organize regular workshops to set science priorities



Science Development Division ALMA will attract a broad spectrum of users, far beyond the

historical NRAO mm/radio userbase. For U.S. astronomers to fully realize the transformational nature of ALMA requires a broader functionality for the ALMA Science Center.

• Advanced User Support• Expert post-observation user support• Support for special, large, and legacy projects• Reprocessing complex datasets• New algorithms for calibration/imaging• Advanced simulation development• Develop advanced observation planning tools

• Professional Development (student programs, schools and workshops)• ALMA Fellows and Postdoc Program• ALMA EPO• User Grants program advocate (could be run by NSF)?• Community involvement in advanced ALMA ‘ops’?

While the Science Operations (ARC) and Science Development Divisions are functionally separate, the scientific staff of the NAASC will be assigned both Operations and Development functions, ensuring that all NAASC astronomers have the proper expertise with end-to-end ALMA operations.



The North American ALMA Science Center (NAASC): summary

Three major components:• The North American ARC Operations

• Basic user support• Mirror of ALMA Archive• Bilaterally agreed upon services

• ALMA Technical Support • Maintenance & Repair of NA delivered hardware/software • Development of additional observing capabilities/techniques

• Science Development Division• Full user support• Fellows, postdocs,student programs, workshops, schools • EPO• User Grants program



User Grants Program Advocate (need not be managed by NRAO)

• $10M user data analysis grants program (US$2013)• Grants tied to successful observing proposals

• Would provide ~$50k to ~200 project of average size ~12hrs

• Strongly endorsed by last Decadal Report for Astronomy & Astrophysics for all new NSF funded facilities

• Positive response from ANASAC, ALMA Town Meetings

• For comparison, other user grants programs:• HST: $28M/yr

• Spitzer: $22M/yr

• Chandra: $12M/yr

• Herschel: $9M/yr planned



NAASC Staff Requirements in 2013

• Science Division (11; 6.5 FTE) – Division head, 6 for proposal support, from submission to verification of observing blocks, plus 4 for data support (retrieval from archive and data reduction); this team has other duties, including duty at Array in Chile; estimate based on experience at VLA/VLBA plus Spitzer system; plus division head;

• Data Management (24 FTE) – 10 S/W Engineers for software maintenance, plus 7 S/W developers, plus 5 for maintaining archive, plus division head and deputy; estimate based on widespread experience that operations team = construction team in software;

• Technical Work in NTC (25; 23 FTE) – 12 for maintenance of hardware, plus 11 for development of new instrumentation and two co-ops; estimate obtained from NTC based on years of experience in hardware maintenance and development, including ALMA construction;

• Science Development (29; 11.1 FTE) – 12 Postdocs, 2 students, 5 education/public outreach; 7 for advanced support of users; 2 to run postdoc/predoc/summer school programs; 1 user grant administrator; estimate based on increment required in NRAO outreach program and in NAASC user support for ALMA;

• (7) Chilean Affairs; (3) NAASC Head, ARC manager, & admin. aide.

NAASC Status: • C. Carilli replaces P. Vanden Bout as NAASC head May 1 2006. • J. Hibbard is Acting Head of NA ARC. C. Brogan is head of ARC Science Division (a division of 1!).• An internal review of the “NA ALMA Operations and NAASC Staffing Plan” was held on April 11th.

Panel members included representatives from GBT Ops, NM Ops, e2e, EVLA, Fiscal, HR, the Directors Office, and NRC. Overall the response was positive.

• Discussions were held concerning the role of Canada in NA ALMA operations. James Di Francesco is official NRC liasion to NAASC. NRC-HIA will comment on the NAASC Staffing plan and get back to us with concrete suggestions.

• Presentations on the NAASC were made to NSF on April 24 2006. A formal proposal is due to NSF by the end of October 2006. NSF priorities are (1) support for ALMA Chilean Operations; (2) support for bilaterially agreed-upon operations support (i.e., NA ARC); (3) additional NAASC services.

• “ALMA North American Science Advisory Committee” (ANASAC) meets with NAASC and NRAO Director via telecon once every other month.

• NAASC holds informational and planning meetings on first Wednesday of each month. Attended by NRC representative, NRAO ALMA construction personnel, and any interested NRAO staff.

• First NAASC Workshop “From z-Machines to ALMA: (sub)mm Spectroscopy of Galaxies” was held at NAASC Jan 13-14 2006. 75 participants. Wildly successful. Programs and talks posted at http://www.cv.nrao.edu/naasc/zmachines/. Next workshop under discussion with ANASAC.

• Town Meetings held at last two winter AAS meetings. Talks posted at http://www.cv.nrao.edu Special Session planned for Calgary AAS. Presence planned at IAU (Prauge, August) and ALMA Madrid meeting (November), plus AAS Jan 2007.

• Work has begun on defining international EPO working group to facilitate collection and disemmination of “All Things ALMA”. Plans for ALMA Chilean EPO are being developed.

• NAASC webpage: http://www.cv.nrao.edu/naasc/. Work has been done on developing mm/submm calibrator & spectral line databases

• NAASC Personnel participate in tests of all major software systems (PST, pipeline, offline)
