As a follow-up to the 20th edition of the European Fusion Theory Conference, a collection of papers will be published in the Journal of Plasma Physics (JPP). This collection is intended as a Special Issue of a regular journal. Thus, papers are expected to be of high quality and will undergo a standard review. The invited papers in this special collection address the wide range of topics represented in this conference, from basic plasma physics theory to turbulent and neoclassical transport, fast particles, heating and current drive, macroinstabilities, magnetic confinement devices and computational modelling. We encourage all speakers and poster presenters to the conference to submit contributions. There will be no publication charges.
