Internal transport barriers in tokamak plasmas are explored in order to improve confinement
and stability beyond the reference scenario, used for the ITER extrapolation, and to achieve …

MAST plasmas with a safety factor above unity and a profile with either weakly reversed
shear or broad low-shear regions, regularly exhibit long-lived saturated ideal …

In the full tungsten environment of WEST, during its first phase of operation, around 25% of
the pulses exhibited a rapid central electron temperature collapse. In its first phase, WEST …

The new full-metal ITER-like wall (ILW) at JET was found to have a profound impact on the
physics of disruptions. The main difference is a significantly lower fraction (by up to a factor …

Achieving a successful plasma current ramp-up in a full tungsten tokamak can be
challenging due to the large core radiation (and resulting low core temperature) that can be …

MHD spectroscopy in FTU has revealed high frequency (HF) oscillations between 30 and 70
kHz that accompany the development of large m 0=− 2, n 0=− 1 islands in ohmic plasmas …

The publication provide further insights into the dynamics of JET runaway electron (RE)
beams mitigated by D2-rich shattered pellet injection (SPI)(Reux et al 2022 Plasma Phys …

The initial current ramp phase of JET hybrid plasmas is used to optimise the target q-profile
for main heating to allow access to high β and avoid MHD instabilities. Mixed protium …

In this paper lower hybrid current drive (LHCD) experimental milestones paving the way for
future experiments are briefly summarized. The current drive efficiency scaling with the …

Electron temperatures in excess of 8 keV have been obtained by electron-cyclotron-
resonance heating on FTU plasmas at peak densities up to 8× 10 19 m− 3. The magnetic …
