Proposals for observations with the IRAM telescopes may be submitted twice per year through the Proposal Management System PMS. The submission period starts about two to three weeks before a deadline. Submission deadlines are currently around mid-March and mid-September each year for the summer (01 June - 30 November) and winter (01 December - 31 May) scheduling periods. Exact dates and all other relevant information are given in a separate Call for proposals published on the web by mid-February for the summer deadline and by early-August for the winter deadline. In case of problems, please contact the IRAM scientific secretary. Additional detailed technical information can be found on the web pages for the NOEMA interferometer and for the 30m telescope.

Calendar

Semester: 01 December 2022 - 31 May 2023

Shortly after a submission deadline the scientific secretariat sends acknowledgements of receipt to the principal investigators of all proposals received. These receipts are sent by Email and contain the official registration number of the proposal.

Proposals are evaluated at the next meeting of the IRAM program committee and recommendations are made to the IRAM Direction. Proposals are rated A (accepted), B (backup, scheduled under certain favourable conditions), or C (rejected). The program committee has fifteen non-IRAM members plus the ex-officio members: IRAM direction, 30m station manager, and the scientific coordinators of NOEMA and the 30-meter telescope.
