86. Electron Cyclotron Current Drive in DEMO Plasmas (I.8)

Emanuele Poli

10/2/23, 4:00 PM

Invited

Electron cyclotron (EC) waves offer several advantages as a heating scheme in a tokamak fusion reactor, both from the technological (the launchers require small slots in the blanket; the first tritium barrier can be incorporated into the vacuum vessel) and the physical (easy wave-plasma coupling; localized absorption) point of view. The most crucial applications of EC waves in a reactor are the...

8. Transient versus steady state solutions: a qualitative study on tokamak plasma heating (O.5)

Dirk Van Eester

10/2/23, 4:40 PM

Oral

The numerical study of steady state solutions of equations describing the particle and energy balance rightfully gets ample attention since the ultimate goal of fusion research is to produce long-lasting quasi-stationary discharges in future fusion power stations. Transient states may, however, differ significantly from the steady state ultimately reached and will - in practice - impact on the...

66. Resonant Mode-Particle Interactions and Transport Barriers in toroidal plasmas under the presence of an Edge Radial Electric field (O.6)

Ioannis Kominis

10/2/23, 5:05 PM

Oral

Resonant mode-particle interactions crucially determine particle, energy and momentum transport and confinement performance in fusion devices. Non-axisymmetric perturbative modes exist either due to intrinsic instabilities, or due to intentionally applied magnetic fields and affect particles with specific kinetic characteristics by modifying specific locations of the particle’s phase space [1]...
