SOLEIL Financial Assistance


By European Union



Up to 3 users from French institutions (without any regions distinction), in the framework of an accepted experiment by peer review committees, are subsidized for subsistence (guest house and meals at SOLEIL restaurant).                                                            

Financial support for transport applies only for users whose institutes are located outside Ile de France region.

Subsidized users are:

  • Users from outside Ile de France Region
  • At least one subsidized user from Ile de France Region institute

In case of guest house overbooking, subsidized users declared to have priority by the Main proposer, according to the above mentioned rule will be accommodated, by the travel office, in a hotel close to SOLEIL.

Visits to SOLEIL are reimbursed from one day before the dates allocated for the experiment, in order to allow experiment preparation and/or sample disposal.

SOLEIL does not reimburse users from industrial laboratories or from foreign institutions.



By European Union




The CALIPSOplus Consortium brings together 19 partners offering access to 14 synchrotrons and 8 FELs in Europa and the Middle East. The key aims of the project are as follows:

  • Improvement of trans-national cooperation and distribution of knowledge, in particular from countries with a highly developed scientific infrastructure to scientifically less active regions
  • Removing barriers for access to world-class accelerator-based lightsources in Europe and in the Middle East
  • Teaching new users how to successfully use synchrotrons and FELs.
  • Collaborating on constantly developing technology to keep the facilities at the cutting-edge
  • Tailor-made support and access programmes for SMEs

In the framework of the EU CALIPSOplus TransNational Access programme, SOLEIL provides limited financial support for users who participate to an experiment related to an accepted proposal by the SOLEIL Peer Review Committees.
