Effect of front surface engineering on high energy electron, X-ray and heavy ion generation from Relativistic laser interaction with thick high-Z targets
Cette étude menée sur le laser Scarlet démontre que, bien que des revêtements de faible densité puissent théoriquement améliorer le couplage laser-cible, les revêtements testés sur des cibles de tantale trop épaisses ont réduit l'intensité incidente, rendant les cibles nues plus efficaces pour la génération d'électrons et de rayons X, tandis que les revêtements en mousse et nanofils ont favorisé l'accélération d'ions lourds, soulignant ainsi l'importance critique du contrôle de la densité et de l'épaisseur des revêtements.
