The 20th SOLEIL Users’ Meeting will take place from Thursday January 15th to Friday 16th, 2026 at SOLEIL.

This invaluable forum for the synchrotron radiation users’ community will provide the opportunity to exchange and learn about the evolution of the machine and the beamlines.

It will be also the occasion to share scientific, technical and practical issues about the synchrotron radiation use.

 

On Wednesday, January 14, 2026, a workshop "Radiation Damage" will take place at SOLEIL.

The plenary talks will cover the research themes of the following SOLEIL user communities:

  • Soft matter 
  • Geoscience 
     

The parallel sessions will consist of original scientific presentations selected from submitted abstracts.
 

Two social and discussion sessions will be organized at SOLEIL:

  1. Thursday afternoon, January 15, 2026, alongside the « The Synchrotron Community » Posters session, company booths, and a buffet dinner.
  2. Friday morning, January 16, 2026, during the Scientific Posters session followed by the award ceremony for the best student poster and company booths.

Satellites and tutorials will also be held on Friday afternoon, January 16, 2026, at SOLEIL. Further details about the satellites and tutorials will be communicated later.
A thematic workshop "Radiation Damage" will be held on Wednesday 14th of January, 2026 at SOLEIL.

Further information will be available soon.
