Differential clock comparisons with a multiplexed optical lattice clock

Multiple ultracold ensembles of strontium atoms are trapped in the same optical lattice, realizing a multiplexed optical clock where precision measurements can benefit from having all atoms share the same trapping light and clock laser.

A control oriented strategy of disruption prediction to avoid the configuration collapse of tokamak reactors

Confining plasma and managing disruptions in tokamak devices is a challenge. Here the authors demonstrate a method predicting and possibly preventing disruptions and macroscopic instabilities in tokamak plasma using data from JET.

Enhanced performance in fusion plasmas through turbulence suppression by megaelectronvolt ions

Experiments at the Joint European Torus tokamak show improved thermal ion confinement in the presence of highly energetic ions and Alfvénic instabilities in the plasma.

Disruption prediction with artificial intelligence techniques in tokamak plasmas

Tokamak plasmas are prone to sudden collapses that terminate the nuclear fusion reactions. This perspective discusses the prediction of these so-called disruptions with artificial intelligence techniques.
