Infrastructures and Transnational Access (TNA)

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

Monthly TNA event (Zoom)

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

The first two TNA events presented:

The third edition of this event is scheduled for Monday, 25.10.2021, at 15:30 (Brussels time) and will feature a presentation of the IANAO Rozhen Observatory, as well as a general overview on transnational access and time for questions and answers.

Brief definition of transnational access (TNA)

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.
