High-dimensional inverse design of inertial fusion implosions via differentiable simulation
A. J. Crilly, P. Travis, J. P. Brodrick +2
Inertial confinement fusion implosion design requires simultaneous optimisation of strongly coupled target and driver parameters across high-dimensional design spaces. Existing aut…
NeSST: A Python Tool for Neutron Spectra and Synthetic Diagnostics in Inertial Confinement Fusion
Aidan Crilly
We present the Neutron Scattered Spectra Tool (NeSST), an open-source Python package for rapidly constructing primary and singly scattered neutron spectra from inertial confinement…
Enhanced Hot Electron Preheat Observed in Magnetized Laser Direct-Drive Implosions
M. Cufari, M. Gatu Johnson, C. K. Li +5
Hard x-ray emission, associated with hot electron preheat, in direct-drive implosions was observed to be enhanced by a factor of by application of a T magnetic fie…
Fusion alpha particle momentum deposition in thermonuclear burn dynamics
A. J. Crilly, B. D. Appelbe, E. A. Ferdinandi +6
In inertial confinement fusion, the DT fusion alpha particles carry not only energy but also appreciable momentum that is typically neglected in models of thermonuclear burn. In th…
Automated simulation-based design via multi-fidelity active learning and optimisation for laser direct drive implosions
A. J. Crilly, P. W. Moloney, D. Shi +1
The design of inertial fusion experiments is a complex task as driver energy must be delivered in a precise manner to a structured target to achieve a fast, but hydrodynamically st…
Distortions in Charged-Particle Images of Laser Direct-Drive Inertial Confinement Fusion Implosions
P. V. Heuer, J. L. Peebles, J. Kunimune +17
Energetic charged particles generated by inertial confinement fusion (ICF) implosions encode information about the spatial morphology of the hot-spot and dense fuel during the time…
