The high confinement mode (H-mode) is the widely
adopted standard operation scenario for the path
to fusion in toroidal confinement devices. Since
its discovery in 1982, the H-mode and access
to the H-mode (the low to high and high to
low transitions) remain two of the most actively
researched areas in magnetically confined fusion
programmes across the world. Significant progress
has been made in the understanding of the intricate
H-mode phase dynamics in recent years, from
improvement in experimental diagnostic capability,
theoretical development and modelling. The ‘H-mode
transition and pedestal studies’ Special Issue provides
a timely overview of recent progress in the study
of H-modes covering experimental studies, further
theoretical inquiry and computational modelling.
