The full programme and proceedings material for the 2026 workshop are available below.
PPCF submission deadline: April 30th, 2027.
How to submit: Invited speakers submit directly to PPCF. Poster presenters were asked to send an early draft to varenna-lausanne@epfl.ch by 14 September 2026 for workshop refereeing; drafts not prepared in time could still be sent to the editors after the workshop and considered for the issue.
Please use the PPCF author guidelines and templates, and when submitting, select the special issue titled: "Special issue on the 2026 joint Varenna–Lausanne International Workshop on the Theory of Fusion Plasmas."
