Fusion-power amplification by compressive hydrodynamic fluctuations
Henry Fetsch, Nathaniel J. Fisch
Compressive fluctuations in hot plasma, including acoustic waves and compressible turbulence, increase the rate of fusion reactions. This power amplification comprises hydrodynamic…
Long-Pulse Fast Ignition in MagLIF
Benjamin Wang, Henry Fetsch, Nathaniel J. Fisch
The fast ignition paradigm for inertial confinement fusion (ICF) allows for extremely high gains but requires fuel to be heated very quickly to outpace hotspot disassembly and ener…
An ignition criterion for inertial fusion boosted by microturbulence
Henry Fetsch, Nathaniel J. Fisch
Turbulence enhances fusion reactivity, enabling ignition at lower temperature. A modified Lawson-like ignition criterion is derived for inertially confined plasmas harboring turbul…
Analytical models for the enhancement of fusion reactivity by turbulence
Henry Fetsch, Nathaniel J. Fisch
The reactivity of fusion plasma depends not only on its local density and temperature but also, through a recently identified kinetic effect, on the relative velocities of nearby f…
Enhancement to Fusion Reactivity in Sheared Flows
Henry Fetsch, Nathaniel J. Fisch
Sheared flow increases the reactivity of fusion plasma. In unmagnetized plasma with flow gradients comparable to the mean free path of reacting ions, fusion reactivity can be more…
Image rotation in plasmas
Renaud Gueroult, Shreekrishna K. Tripathi, Jia Han +3
Because of the speed of light compared to material motion, the dragging of light is difficult to observe under laboratory conditions. Here we report on the first observation of ima…
