Using the Frontier supercomputer, the WarpX team produced a 3D simulation at scale of their own novel concept: a combined plasma particle injector and accelerator, which focuses a high-power femtosecond (1 quadrillionth of a second) laser onto a hybrid solid/gas target. The simulation’s predictions were later validated by a proof-of-concept experiment performed on the Salle Jaune laser at Laboratoire d’Optique Appliquée in France by Adrien Leblanc and other CEA collaborators.
