Enhancement to Fusion Reactivity in Sheared Flows

Sheared flow increases the reactivity of fusion plasma. In unmagnetized DT plasma with flow gradients comparable to the mean free path of reacting ions, reactivity can be more than doubled.

description Sheared flow increases the reactivity of fusion plasma. In unmagnetized DT plasma with flow gradients comparable to the mean free path of reacting ions, reactivity can be more than doubled. Neutron spectra are modified, helping to explain anomalous observations. The reactivity enhancement is particularly relevant in inertial confinement fusion (ICF), where it allows turbulent kinetic energy to contribute to the fusion burn even before thermalizing. In high-yield ICF experiments, the effect is most pronounced before bang time, suggesting a new mechanism for fast ignition.
