Development of quick and remote analysis for severe accident reactor, 4-3; The Effects of focus optimization for laser induced breakdown spectroscopy

Akaoka, Katsuaki ; Oba, Masaki ; Miyabe, Masabumi ; Wakaida, Ikuo

In the elementary analysis using Laser Induced Breakdown Spectroscopy (LIBS), the intensity of the LIBS spectrum and plasma temperature is changed by the focus position of the laser beam. Therefore we inspected the effect of the optimization of the focus to reduce the instability of spectrum intensity.
