Abstract

Abstract

This article intoduces the principle of extended X-ray absorption fine structure(EXAFS) as parameter diagnostic method on large laser facilities, as well as the experiments on SG-III prototype facility for high quality EXAFS. Using glass ball, CH capsule and Au ball as backlighters, through multi-shots accumulation method, EXAFS of Ti in ambient condition with good signal-to-noise ratio were obtained. The experiment results coincide well with the results of the synchrotron radiation experiment, indicating the correctness and reliability of the experimental design. Analysis of the results show the factors affecting the EXAFS spectrum quality are photon counts, spectral resolution, noise and flaws on apparatuses.
