29th EU-US Transport Task Force Workshop - 2025

Registration and abstract submission are now open.


The LOC is happy to announce that the 2025 EU-US Transport Task Force Workshop will be hosted by the HUN-REN Centre for Energy Research, based in Budapest, Hungary.

The goal of the EU-US Transport Task Force (TTF) is to develop a physics-based understanding of particle, momentum and heat transport in magnetically confined fusion plasmas. This understanding should be of sufficient depth that it allows the development of predictive models of plasma transport that can be validated against experiment, and then used to simulate the future performance of burning plasmas and aid the design and optimization of next-step fusion energy reactors. To achieve success in transport science, it is essential to characterize local fluctuations and transport in fusion grade plasmas, to understand the basic mechanisms responsible for transport, and ultimately to control these transport processes. These goals must be pursued in multiple research thrusts, and the TTF workshop focus topics evolve to reflect emerging advances in physics understanding.


Paper submission to IOP Plasma Physics and Controlled Fusion 

The Programme Committee has obtained an agreement with the IOP Plasma Physics and Controlled Fusion (PPCF) Editorial Board for a Special Issue to be published with the 29th EU-US TTF meeting. This will enhance visibility for both your work and our collective effort as a group.
Participants are encouraged to submit a manuscript of the extended paper of your contributions.

To best align with your research timescales, the Special Issue will be published online and extended as articles are reviewed with a rolling deadline. Submissions will be open for a year after the meeting and available at least 3 months ahead.

*The Programme Committee strongly requests invited and plenary speakers to contribute their work to the Special Issue.
