概要
We proposed a novel sodium leak detection technique based on laser spectroscopy to improve the reliability of sodium le ak monitoring. In this technique, sodium atoms are excited into a first excitation level by atmospheric plasma before l aser spectroscopy. The detection limit concentration was preliminarily evaluated to be comparative to the sodium aeros ol detector. We confirmed that the maximum of 3p level population can be achieved at a proper plasma burning condition.
