Decomposition-Guided Diffusion Language Models for Inertial Confinement Fusion Prediction
Xiang Zhang, Varchas Gopalaswamy, Rahman Ejaz +2
Inertial confinement fusion (ICF) is a leading pathway toward clean energy, but each shot at the National Ignition Facility costs on the order of one million dollars, making accura…
A Hybrid Scheme to Achieve Highest Implosion Performance on the OMEGA Laser
P. S. Farmakis, L. Ceurvorst, V. Gopalaswamy +5
Merging direct and indirect-drive has long been viewed as an optimal hybrid laser-fusion scheme that combines the uniformity of x rays with the efficiency of direct illumination. W…
Human-in-the-Loop Meta Bayesian Optimization for Fusion Energy and Scientific Applications
Ricardo Luna Gutierrez, Sahand Ghorbanpour, Ejaz Rahman +6
Inertial Confinement Fusion (ICF) holds transformative promise for sustainable, near-limitless clean energy, yet remains constrained by prohibitively high costs and limited experim…
BayMOTH: Bayesian optiMizatiOn with meTa-lookahead -- a simple approacH
Rahman Ejaz, Varchas Gopalaswamy, Ricardo Luna +5
Bayesian optimization (BO) has for sequential optimization of expensive black-box functions demonstrated practicality and effectiveness in many real-world settings. Meta-Bayesian o…
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…
Can Kans (re)discover predictive models for Direct-Drive Laser Fusion?
Rahman Ejaz, Varchas Gopalaswamy, Riccardo Betti +2
The domain of laser fusion presents a unique and challenging predictive modeling application landscape for machine learning methods due to high problem complexity and limited train…
Neutron backscatter edge: A measure of the hydrodynamic properties of the dense DT fuel at stagnation in ICF experiments
Aidan J. Crilly, Brian D. Appelbe, Owen M. Mannion +3
The kinematic lower bound for the single scattering of neutrons produced in DT fusion reactions produces a backscatter edge in the measured neutron spectrum. The energy spectrum of…
Analysis of trends in experimental observables and reconstruction of the implosion dynamics for direct-drive cryogenic targets on OMEGA
A. Bose, R. Betti, D. Mangino +22
This paper describes a technique for identifying trends in performance degradation for inertial confinement fusion implosion experiments. It is based on reconstruction of the implo…
