Scaling laws for energetic ions from the commissioning of the new Los Alamos National Laboratory 200 TW Trident lasera)
Abstract
The recent Los Alamos National Laboratory Trident laser enhanced from 30 to 200 TW in power allows more than 100 J to be delivered on target in 500 fs with a spot size smaller than 12 μm at full width at half maximum. 15 μm flat-foil targets have been observed to produce proton beams in excess of 50 MeV at an intensity of only ∼4×1019 W/cm2 with efficiencies approaching 5%. The Trident laser beam characteristics are presented along with the data compared to published scaling laws for proton acceleration.
