Infrastructures for Trans-national Access (TA)

ChETEC-INFRA provides transnational access to the 13 infrastructures networked in the project. New and outside users are especially welcome!

Call for Proposals

Proposals can be submitted through the GATE server continuously. The independent user selection panel meets every three months. The next collection date is August 17, 2024.

How to Apply


TA User Office

Brief definition of transnational access (TA)

Transnational access by scientific users

  • crosses national borders (i.e. users must use an installation located outside the country where they work),
  • is free of charge to the users (access fees to the facilities are paid by the European Union),
  • may include travel support for the users, again funded by the EU,
  • should generally foresee to publish the scientific results,
  • is open to scientists of all nationalities and based in all countries (with limits on the amount of access given to users outside the EU and associated countries),
  • is allocated by an independent user selection panel, solely based on scientific merit.

Details on the transnational access scheme are shown in this presentation (4 May 2021). The detailed eligibility and scoring criteria are given on this page.

Weekly TA "Office Hours"

For questions and information on transnational access, open Zoom meetings takes place Monday between 14:30 and 15:00 at this meeting link. In case of holidays etc. please confirm with the calendar.

Monthly TA event (Zoom)

You are invited to attend our monthly TA event on Zoom, which features one of the ChETEC-INFRA facilities and allows users to ask any question they may have on Trans-national Access.

TA events presented so far:

The TA event series will be continued.
