Description

Laser-driven proton acceleration, obtained by irradiation of a solid by an ultra-intense (I>10e18 W/cm2) short pulse (duration<1 ps) laser, is a growing field of interest, in particular for its manifold potential applications in different fields. In this letter, we provide first experimental evidence that laser-generated protons can be used for stress testing materials and are particularly suited for stress-testing material in harsh condition. We show that laser-generated protons can produce, in a few single ns shots, a similar mechanical and thermal stress than what obtained during several months of full operation for typical fusion or reactor facilities. We confirm this by analyzing changes in mechanical, optical, electrical, and morphological properties of five materials of interest to be used in harsh conditions.
