Calibración absoluta y aplicación de los detectores de pérdidas de iones rápidos basados en materiales centelleadores para dispositivos de fusión nuclear [PhD Thesis]
(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 ...
Recent ASDEX Upgrade research in support of ITER and DEMO [Article]
(IOP Publishing, 2015)
Recent experiments on the ASDEX Upgrade tokamak aim at improving the physics base for ITER and DEMO to aid the machine design and prepare efficient operation. Type I edge localized mode (ELM) mitigation using resonant ...
Overview of progress in European medium sized tokamaks towards an integrated plasma-edge/wall solution [Article]
(IOP Publishing, 2017)
Integrating the plasma core performance with an edge and scrape-off layer (SOL) that leads to tolerable heat and particle loads on the wall is a major challenge. The new European medium size tokamak task force (EU-MST) ...
Overview of ASDEX Upgrade results [Article]
(IOP Publishing, 2017)
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, ...
Overview of the JET results in support to ITER [Article]
(IOP Publishing, 2017)
The 2014–2016 JET results are reviewed in the light of their significance for optimising the ITER research plan for the active and non-active operation. More than 60 h of plasma operation with ITER first wall materials ...
Fast-ion redistribution and loss due to edge perturbations in the ASDEX Upgrade, DIII-D and KSTAR tokamaks [Article]
(IOP Publishing, 2013)
The impact of edge localized modes (ELMs) and externally applied resonant and non-resonant magnetic perturbations (MPs) on fast-ion confinement/transport have been investigated in the ASDEX Upgrade (AUG), DIII-D and ...
Beam-Ion Acceleration during Edge Localized Modes in the ASDEX Upgrade Tokamak [Article]
(American Physical Society, 2018-07)
The acceleration of beam ions during edge localized modes (ELMs) in a tokamak is observed for the first time through direct measurements of fast-ion losses in low collisionality plasmas. The accelerated beamion population ...
Velocity-space resolved measurements of fast-ion losses due to magnetohydrodynamic instabilities in the ASDEX Upgrade tokamak. [PhD Thesis]
(2018-12-17)
The confinement of suprathermal ions in magnetically confined fusion plasmas is essential to ensure a good fusion performance. Auxiliary heating systems - and fusion reactions themselves - create fast-ion populations, which ...
Measurement of a 2D fast-ion velocity distribution function by tomographic inversion of fast-ion D-alpha spectra [Article]
(OP Publishing, 2014)
We present the first measurement of a local fast-ion 2D velocity distribution function f(v||, v⊥). To this end, we heated a plasma in ASDEX Upgrade by neutral beam injection and measured spectra of fast-ion Dα (FIDA) light ...
Overview of the JET preparation for deuterium–tritium operation with the ITER like-wall [Article]
(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 ...
