| 内容記述 | Currently throughout the world there has been a rapid increase in the number of ultra-high power petawatt-class laser facilities. These lasers have been shown via the interaction of plasmas to produce high energy electrons, protons and gamma rays. As the laser power increases the potential to produce ultra-high flux polarized gamma ray sources has been shown both theoretically and numerically via particle-in-cell simulations. One potential use of such gamma ray sources is the study of quantum electrodynamics (QED), which describes the interaction of photons with electrons. Although QED has been tested experimentally and found to agree with experiments to high precision to lowest order, higher order measurements are needed to test QED and determine whether there could be new as yet undiscovered phenomena. Delbrück scattering is a higher order process, which involves the scattering of photons off the Coulomb fields of nuclei, and is the only one which has been measured due to its large cross section. We have found recently that polarized gamma ray sources can achieve high precision measurements of Delbrück scattering. Therefore, these ultra-high power facilities offer the possibility of measuring Delbrück scattering to high precision. Along with an introduction and conclusion we will review the physics of Delbrück scattering, high flux polarized gamma-ray sources from laser-plasma and laser-electron beam interactions, and the numerical techniques to calculate the Delbrück scattering cross section. | |||||
