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 may 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.

The TNA event on Monday, 26.07.2021, 15:30 – 16:30 (Brussels time) will include brief presentations outlining TNA in ChETEC-INFRA, and a session dedicated to one particular facility, in that case the Felsenkeller underground ion accelerator. The rest of the session will be devoted to questions and answers. The session will be recorded and published on Youtube. The link can be found here:

We plan to have further „TNA day“ sessions in September and October, each featuring a different ChETEC-INFRA infrastructure.

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.

Facilities offering access

Facilities with transnational access include Astronuclear Laboratories (), Astronuclear High-Performance Computing () and Astronuclear Telescopes ():
