A Physics-Informed Deep Learning Description of Knudsen Layer Reactivity Reduction

Christopher J. McDevitt, Xian-Zhu Tang

A physics-informed neural network (PINN) is used to evaluate the fast ion distribution in the hot spot of an inertial confinement fusion target. The use of tailored input and outpu…

A Physics-Informed Deep Learning Model of the Hot Tail Runaway Electron Seed

Christopher McDevitt

A challenging aspect of the description of a tokamak disruption is evaluating the hot tail runaway electron (RE) seed that emerges during the thermal quench. This problem is made c…

Runaway electron current reconstitution after a non-axisymmetric magnetohydrodynamic flush

Christopher J. McDevitt, Xian-Zhu Tang

Benign termination of mega-ampere (MA) level runaway current has been convincingly demonstrated in recent JET and DIII-D experiments, establishing it as a leading candidate for run…

The constraint of plasma power balance on runaway avoidance

Christopher J. McDevitt, Xian-Zhu Tang, Christopher J. Fontes +2

In a post-thermal-quench plasma, mitigated or unmitigated, the plasma power balance is mostly between collisional or Ohmic heating and plasma radiative cooling. In a plasma of atom…

Impact of a minority relativistic electron tail interacting with a thermal plasma containing high-atomic-number impurities

Nathan A. Garland, Hyun-Kyung Chung, Christopher J. Fontes +6

A minority relativistic electron component can arise in both laboratory and naturally-occurring plasmas. In the presence of high-atomic-number ion species, the ion charge state dis…

Self-similar structure and experimental signatures of suprathermal ion distribution in inertial confinement fusion implosions

Grigory Kagan, D. Svyatskiy, H. G. Rinderknecht +4

The distribution function of suprathermal ions is found to be self-similar under conditions relevant to inertial confinement fusion hot-spots. By utilizing this feature, interferen…
