Users support

Helpdesk: the ALMA Helpdesk must be used for any enquiry. Note that you must be registered as ALMA user to submit a ticket to the helpdesk.

Phase II support: each project is assigned a Contact Scientist in one of the ARC nodes, who interacts with the PI to discuss and validate the Science Goals (SGs) that have been created from the initial proposals. The role of the ALMA Contact Scientist is similar to that of the NOEMA Local Contact.


Face-to-face support: if needed, the PI can request direct assistance from an ARC node of their choice to reduce ALMA data or prepare ALMA proposals. For this, the PI should submit a Helpdesk ticket: once logged in, select "Submit a Ticket", and then the category "Face to Face Support (EU)". It is not necessary to be a partner of IRAM in order choose this ARC node for a face-to-face visit. Access the visitors schedule at IRAM.

IMPORTANT: As of 18 March 2020, face-to-face support at IRAM is suspended due to COVID-19 until further notice. Remote support is possible only on a best effort basis since 25 May 2020. Read the IRAM update here.

Travel funding:
  • IRAM travel funding is available for visiting astronomers following the same rules as for NOEMA data reduction: one trip, one person per project. Only scientists affiliated to the IRAM funding agencies are elligible for this financial support ⇒ financial support rules.
  • Alternatively, MARCUS funding can be requested by visiting astronomers provided they have an EU affiliation and are not funded under any other EU grant. To do so, a MARCUS funding request should be submitted.
