<< The challenge of fusion energy is often equated to capturing- and holding-lightning in a bottle. The analogy is apt. Lightning and a fusion energy plasma have a lot in common >> [1]

<< Intermittent bursts of activity indicate that whistlers are interacting with relativistic electrons in a cyclic manner >> [1]
<< The mode amplitudes show intermittent time variations correlated with changes in the electron cyclotron emission that follow predator-prey cycles >> [2]
<< the Team thinks there is a way to inject whistlers into a plasma to control runaway electrons. The whistlers would bleed energy from the particles, making them less likely to run away. The whistlers would bleed energy from the particles, making them less likely to run away.>> [1]
