Optimizing beam-ion confinement in ITER by adjusting the toroidal phase of the 3D magnetic fields applied for ELM control
(IOP Publishing, 2021-03)
The confinement of neutral beam injection (NBI) particles in the presence of n = 3 resonant magnetic perturbations (RMPs) in 15 MA ITER DT plasmas has been studied using full orbit ASCOT simulations. Realistic NBI distribution ...

Multi-machine scaling of the main SOL parallel heat flux width in tokamak limiter plasmas
(IOP Publishing, 2016-07)
As in many of today’s tokamaks, plasma start-up in ITER will be performed in limiter configuration on either the inner or outer midplane first wall (FW). The massive, beryllium armored ITER FW panels are toroidally shaped ...

Long-term fuel retention and release in JET ITER-Like Wall at ITER-relevant baking temperatures
(IOP Publishing, 2017-08)
The fuel outgassing efficiency from plasma-facing components exposed in JET-ILW has been studied at ITER-relevant baking temperatures. Samples retrieved from the W divertor and Be main chamber were annealed at 350 and ...

Overview of ASDEX Upgrade results
(IOP Publishing, 2017-10)
The ASDEX Upgrade (AUG) programme is directed towards physics input to critical elements of the ITER design and the preparation of ITER operation, as well as addressing physics issues for a future DEMO design. Since 2015, ...

Asymmetric toroidal eddy currents (ATEC) to explain sideways forces at JET
(IOP Publishing, 2016-10)
During some JET vertical displacement events (VDEs) plasma current and position are found to be toroidally asymmetric. When asymmetries lock, the vessel has been observed to move horizontally, consequently strong horizontal ...

Multi-machine analysis of termination scenarios with comparison to simulations of controlled shutdown of ITER discharges
(IOP Publishing, 2018-02)
To improve our understanding of the dynamics and control of ITER terminations, a study has been carried out on data from existing tokamaks. The aim of this joint analysis is to compare the assumptions for ITER terminations ...

Beryllium migration in JET ITER-like wall plasmas
(IOP Publishing, 2015)
JET is used as a test bed for ITER, to investigate beryllium migration which connects the lifetime of first-wall components under erosion with tokamak safety, in relation to long-term fuel retention. The (i) limiter and ...

Assessment of the baseline scenario at q(95) similar to 3 for ITER
(IOP Publishing, 2018-12)
The International Tokamak Physics Activity topical group on integrated operational scenarios has compiled a database of stationary H-mode discharges at q95 ~ 3 from AUG, C-Mod, DIII-D, JET and JT-60U, for both carbon ...

Overview of physics studies on ASDEX Upgrade
(IOP Publishing, 2019-11)
The ASDEX Upgrade (AUG) programme, jointly run with the EUROfusion MST1 task force, continues to significantly enhance the physics base of ITER and DEMO. Here, the full tungsten wall is a key asset for extrapolating to ...
