Overview of the JET preparation for deuterium–tritium operation with the ITER like-wall
(IOP Publishing, 2019-08-30)
For the past several years, the JET scientific programme (Pamela et al 2007 Fusion Eng. Des. 82 590) has been engaged in a multi-campaign effort, including experiments in D, H and T, leading up to 2020 and the first ...

Electron cyclotron heating can drastically alter reversed shear Alfven eigenmode activity in DIII-D through finite pressure effects
(IOP Publishing, 2016-11)
A recent DIII-D experiment investigating the impact of electron cyclotron heating (ECH) on neutral beam driven reversed shear Alfvén eigenmode (RSAE) activity is presented. The experiment includes variations of ECH ...

Improved ERO modelling of beryllium erosion at ITER upper first wall panel using JET-ILW and PISCES-B experience
(Elsevier, 2019-05)
ERO is a 3D Monte-Carlo impurity transport and plasma-surface interaction code. In 2011 it was applied for the ITER first wall (FW) life time predictions [1] (critical blanket module BM11). After that the same code was ...

Real-time plasma state monitoring and supervisory control on TCV
(IOP Publishing, 2019-02)
In ITER and DEMO, various control objectives related to plasma control must be simultaneously achieved by the plasma control system (PCS), in both normal operation as well as off-normal conditions. The PCS must act on ...

Excitation of Toroidal Alfvén Eigenmodes with Counter-current NBI in the TCV Tokamak
(Institute of Physics Publishing, 2023)
In Tokamak á Configuration Variable (TCV), unstable modes excited by resonant interaction between the shear Alfvèn waves in continuum gaps and energetic particles have been observed in scenarios with neutral beam injection ...

Current Research into Applications of Tomography for Fusion Diagnostics
(Springer, 2018-08-23)
Retrieving spatial distribution of plasma emissivity from line integrated measurements on tokamaks presents a challenging task due to ill-posedness of the tomography problem and limited number of the lines of sight. Modern ...

Effect of PFC Recycling Conditions on JET Pedestal Density
(Wiley Online Library, 2016-08)
There is experimental evidence that the pedestal dynamics in type-I ELMy H-mode discharges is significantly affected by a change in the recycling conditions at the tungsten plasma-facing components (W-PFCs) after an ELM ...

Dependence on plasma shape and plasma fueling for small ELM regimes in TCV and ASDEX Upgrade
(2019-08)
Within the EUROfusion MST1 Work Package, a series of experiments has been conducted on AUG and TCV devices to disentangle the role of plasma fueling and plasma shape for the onset of small ELM regimes. On both devices, ...

Calibración absoluta y aplicación de los detectores de pérdidas de iones rápidos basados en materiales centelleadores para dispositivos de fusión nuclear
(2017-09-22)
La fusión nuclear se presenta como una de las pocas opciones energéticas virtualmente inagotable y respetuosa con el medio ambiente. En los actuales dispositivos de fusión nuclear, la existencia de partículas supratérmicas ...
