NA ALMA Develpment FY2023 Call for Study Proposals

The National Radio Astronomy Observatory (NRAO) invites interested parties to submit proposals for Studies to explore potential upgrades for the Atacama Large Millimeter/submillimeter Array (ALMA). Principal Investigators (and funded co-investigators) for NA ALMA Development projects or studies must have as their primary affiliation a US or Canadian institution. The priority for ALMA development is addressing the goals described in the ALMA Development Roadmap  (hereafter called the Roadmap) which lays out the vision for keeping ALMA at the forefront of scientific discovery into the 2030s. The ALMA Partnership is currently pursuing the highest near term priority of the Roadmap which is to at least double (with a an ultimate goal of quadrupling) the system bandwidth of ALMA with improved receiver sensitivity. This initiative is called the ALMA 2030 Wideband Sensitivity Upgrade (WSU). So far development projects are either underway or in an advanced stage of the approval process for an upgraded wideband Band 6 receiver (Band 6v2), to prototype the new wideband digitizers, and to build the 2nd Generation ALMA Correlator. Projects are also underway to complete ALMA's full suite of receiver bands, with Band 1 (35-50 GHz) expected to be available for Cycle 10 and Band 2 (67-116 GHz) expected to be completed within a few years.

Of particular interest to the NA ALMA Partnership for the FY2023 Call are Studies that aim to explore improvements to:

  • ALMA data processing and/or data analysis for the wider bandwidth data that will be produced by the WSU (~two orders of magnitude more channels will be available for high spectral resolution observations)
  • Receiver sensitivity at wide IF bandwidth
  • The ALMA Science Archive / data mining.
  • Longer baseline lengths (2-3x) in the form of a detailed science case (including simulations) that demonstrates the potential for significant science gains. Any ALMA science topic is welcome, apart from dust in protoplanetary disks which have already been studied.

Additionally, Studies on any ALMA-related development topic are welcome. Funded studies and projects from previous calls are summarized including their abstracts and final reports HERE.

Studies for the FY2023 Proposal Call may request up to $200k USD for a duration of up to 1 year to start January 1, 2023. Please note, that apart from demonstration of exceptional circumstances (family or medical leave) only one 6-month No Cost Extension will be granted for successful FY2023 Studies. Therefore the goals for submitted Studies should be commensurate with a 1 year duration.

A Frequently Asked Questions (FAQ) page is available, and will be updated as questions are received and answered. This FAQ includes questions from all past calls in chronological order.

Information/Coordination Meeting - June 7, 2022

An optional informational webinar with question/answer period will be held on June 7, 2022. Registration is required to attend the webinar, see the Coordination Meeting Webpage (coming soon) for more information.

Submission of a Notice of Intent (NOI) is Mandatory

Proposers are required to submit a Project Proposal Notice of Intent by 14, June 2022 (midnight EDT). This will ensure that all Proposers are included in the FY2023 Call mailing list in case of late breaking news, and that proposals can be reviewed in a timely fashion. An NOI is non-binding, but proposals that have not been preceded by an NOI will not be accepted. Please submit your NOI by filling out the following NOI WEB FORM.

NOTE: Prospective NRAO Proposers are required to submit a New Ideas Form for approval by the NRAO Director before proceeding.
