Claims

C1strongest claim

we report the first quantitative measurements of photon spectra (0.1--100 MeV) and angular distributions in the petawatt interaction regime, using an ultra-intense (>10^{21} W/cm^{2}), ultra-short (24 fs) laser pulse. These results are complemented by the characterization of simultaneously produced MeV neutrons. We demonstrate that these neutrons, once moderated, can enable in-depth material identification via resonance transmission analysis.

C2weakest assumption

That the laser-target interaction and chosen diagnostics produce accurate, representative spectra and distributions without major systematic errors or background contamination, and that neutron moderation enables reliable resonance transmission analysis for material identification.

C3one line summary

First quantitative characterization of simultaneous petawatt laser-driven MeV X-ray and neutron beams for dual radiography capability.
