The SPARC tokamak is a critical next step towards commercial fusion energy. SPARC is
designed as a high-field () relevant to fusion power plants. SPARC's place in the path to …

This paper presents an overview of results from L–H transition experiments that were
performed at ASDEX Upgrade (AUG) with the aim of identifying the underlying mechanisms …

We present an overview of results from a series of L–H transition experiments undertaken at
JET since the installation of the ITER-like-wall (JET-ILW), with beryllium wall tiles and a …

An overview of results of negative triangularity (NT) studies from the ASDEX Upgrade
tokamak (AUG) is given. Moderate values of the triangularity in the range of δ average≈ …

The programme to design plasma scenarios for the Spherical Tokamak for Energy
Production (STEP), a reactor concept aiming at net electricity production, seeks to exploit the …

SPARC is designed to be a high-field, medium-size tokamak aimed at achieving net energy
gain with ion cyclotron range-of-frequencies (ICRF) as its primary auxiliary heating …

The paper provides an overview of the results obtained on the spherical tokamak Globus-M2
in 2019–2020. The experiments were performed with the toroidal magnetic field up to 0.8 T …

The work presents the results of the energy confinement study carried out on the compact
spherical tokamak Globus-M2 with a toroidal magnetic field as high as 0.8 T. A reproducible …

The relation between the macroscopic input power required at ASDEX Upgrade to access
the H-mode Pthr and the microscopic E× B shear has been investigated via fast charge …

The current work reports on the significant rise of the fusion triple product in experiments
