Kinetic instabilities driven by runaway electrons (REs) have recently received attention in the
fusion community as a means to control and diagnose REs in a tokamak. Experiments …

Runaway electrons (REs) are a concern for tokamak fusion reactors from discharge startup
to termination. A sudden localized loss of a multi-megaampere RE beam can inflict severe …

The resonant interaction between a runaway electron (RE) beam and a reactor-grade
background plasma is investigated through two-dimensional particle-in-cell simulations …

Electromagnetic waves emitted during a tokamak discharge can be partially ascribed to
coupling with plasma waves. In particular, in the presence of runaway electrons, the …

Optimisation based algorithms known as Moving Horizon Estimator (MHE) have been
developed through the years. In this work, we propose two solutions to decrease the …

Runaway electrons (REs) are a concern for existing nuclear fusion devices and will be a
major threat to future nuclear fusion reactors, like ITER. Therefore, suitable RE mitigation …

This paper discusses the development of a benign termination scenario for runaway
electron (RE) beams on ASDEX Upgrade and TCV. A systematic study revealed that a low …

Shape control is crucial in plasma magnetic confinement due to its direct impact on fusion
efficiency. Traditional controllers focus on minimizing plasma shape errors but often …
