Plasma Diagnostic Using Spectroscopy Techniques at the SMART Tokamak
(2023)
In nuclear fusion, impurities play an important role as they influence the performance of the plasma. To measure their properties, the gas puff based charge exchange recombination spectroscopy (GP-CXRS) diagnostic is ...

Characterization of the ion pedestal in low and high collisionality plasmas
(2017)
The high confinement mode (H-mode) is a very important regime for future fusion devices. In this regime, the global confinement is increased and a pedestal structure is developed in the profiles. However, a complete ...

Characterization of scintillators for ion detection dagnostics in nuclear fusion reactors
(2021)
Abstract Scintillator materials are used for ion detection diagnostics in nuclear fusion devices. These diagnostics obtain information from the plasma in a fusion device, for example, in a tokamak. Scintillators working ...

Feasibility study of a thermal ion loss detector for a magnetically confined fusion device
(2021)
Magnetic confinement devices can be used to confine the plasma and produce fusion. These kind of devices can operate in different plasma regimes. Amongst them, the so called H-mode appears as an attractive alternative ...

Investigation of the separatrix ion temperature using impurity Charge Exchange Recombination Spectroscopy
(2021)
The ion temperature of a magnetically confined plasma plays an important roll in that plasma’s ability to initiate and sustain fusion reactions. In the development of fusion technology it is thus critical to be able to ...

Orbit simulations of fast-ion transport induced by externally applied 3D magnetic perturbations in the ASDEX Upgrade tokamak.
(2018-12)
Externally applied 3D magnetic perturbations break the symmetry of the magnetic field in a tokamak and have an impact on the transport of fast-ions, i.e. suprathermal ions. It was shown that the variation of the toroidal ...

Feasibility Study of an Imaging Charge Exchange Recombination Spectroscopy Diagnostic for Wendelstein 7-X
(2022)
Impurities, which are all the ion species other than the main fuel present in a fusion plasma, play an important role in nuclear fusion, conditioning plasma performance via loss mechanisms such as radiative and transport ...
