Abstract
Official abstract text for this publication.
A system and method for stress testing a sample, the system comprising a high-intensity laser unit and a target for laser-matter interaction, wherein the high-intensity laser unit delivers an intensity of at least 10 13 W/cm 2 on the target, and resulting laser-accelerated particles generated by the target irradiate the sample.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for stress testing a material, comprising determining the heat diffusion and the melting temperature of the material, selecting a laser, positioning a target at a distance from the material; and irradiating the target with the laser, the target generating directional laser-accelerated protons, directing the protons to a surface of the material, and measuring resulting modifications of the material, wherein the laser is selected for emitting a beam of a pulse duration less than 1 ns to deliver an on-target intensity of at least 10 18 W/cm 2 , a material and a thickness of the target and the distance between the target and the material are selected according to an initial temperature, the heat diffusion and the melting temperature of the material and energy and flux of the protons impinging on the material, thereby controlling energy transfer to the material as determined on a selected stress level for the stress testing. 2. The method of claim 1 , wherein the target is a gas. 3. The method of claim 1 , wherein the target is a plasma. 4. The method of claim 1 , wherein the material is a solid. 5. The method of claim 1 , wherein the material is a gas. 6. The method of claim 1 , wherein the material is a liquid. 7. The method of claim 1 , comprising selecting a distance between the target and the laser.
