What is it about?

Plasmas are often heated by injecting a particle beam. This can lead to instabilities that transfer energy to the electric field which is then not available for heating. We show that the mentioned instability can be largely suppressed by choosing a beam intensity that varies in time (i.e. is modulated). The paper determines good choices for the modulated beam intensity by performing numerical optimization.

Why is it important?

Beam heating is commonly used to heat plasmas, e.g. in fusion reactors like ITER. In such situations, it is important to avoid instabilities and have control over the evolution of the plasma.
