Model-based estimation of tokamak plasma profiles and physics parameters: algorithm overview and application to ITER

Olivier Sauter, Federico Alberto Alfredo Felici, Francesco Carpanese, Cassandre Ekta Contré, Reinart Andreas J. Coosemans, Francesco Pastore

Combining dynamic models and measurements into a consistent plasma state estimate is an important challenge for ITER and DEMO, due to the inherent limitations regarding diagnostic coverage in a nuclear fusion reactor environment. In this work, a model-base ...

Spurious radiated power signal following massive material injections in JET and the effect of neutral gas pressure on resistive bolometers

Umar Sheikh

Massive material injections in the JET tokamak have been observed to substantially affect resistive bolometer measurements, resulting in a spurious radiated power signal proportional to the quantity injected and reaching up to 8 MW. These bolometers are ca ...

Analysis and expansion of the quasi-continuous exhaust (QCE) regime in ASDEX Upgrade

Benoît Labit

The quasi-continuous exhaust (QCE) regime, formerly known as either type-II ELM or small ELM regime is studied in ASDEX Upgrade. The regime is a natural type-I ELM-free H-mode. The operational space of QCE discharges in ASDEX Upgrade with respect to their ...

Physics of runaway electrons with shattered pellet injection at JET

Javier García Hernández, Cristian Sommariva

Runaway electrons (REs) created during tokamak disruptions pose a threat to the reliable operation of future larger machines. Experiments using shattered pellet injection (SPI) have been carried out at the JET tokamak to investigate ways to prevent their g ...

Computation of multi-region, relaxed magnetohydrodynamic equilibria with prescribed toroidal current profile

Jonathan Graves, Joaquim Loizu Cisquella, Antoine Baillod

The stepped-pressure equilibrium code (SPEC) (Hudson et al., Phys. Plasmas, vol. 19, issue 11, 2012, 112502) is extended to allow the computation of multi-region, relaxed magnetohydrodynamics (MRxMHD) equilibria at prescribed toroidal current profile. Toro ...

Design Study of a 50-kA React-and-Wind Bi-2212 Cable for Fusion Magnet

Davide Uglietti

In the last few years, the current density of Bi-2212 wires has been greatly improved by filament densify technologies. One further step toward applications in fusion magnets is to design a high current cable, which must overcome the drawbacks of Bi-2212 w ...

Spectral Broadening of Characteristic gamma-Ray Emission Peaks from C-12(He-3, p gamma)N-14 Reactions in Fusion Plasmas

Patrick Blanchard, Gabriele Grosso

The spectral broadening of characteristic gamma-ray emission peaks from the reaction C-12(He-3, p gamma)N-14 was measured in D(He-3) plasmas of the JET tokamak with ion cyclotron resonance heating tuned to the fundamental harmonic of He-3. Intensities and ...

The role of plasma elongation on turbulent transport in magnetically confined plasmas

Laurent Villard, Trach-Minh Tran, Alberto Bottino, Ben McMillan, Sébastien Jolliet, Paolo Angelino

The theoretical study of plasma turbulence is of central importance to fusion research. Experimental evidence indicates that the confinement time results mainly from the turbulent transport of energy, the magnitude of which depends on the turbulent state r ...

Characterizing electron temperature gradient turbulence via numerical simulation

Numerical simulations of electron temperature gradient (ETG) turbulence are presented that characterize the ETG fluctuation spectrum, establish limits to the validity of the adiabatic ion model often employed in studying ETG turbulence, and support the ten ...
