Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)), Sagamihara, Kanagawa Japan, Laser-induced breakdown spectroscopy (LIBS) is a very useful elemental analysis tool in planetary exploration. In this study we conducted LIBS measurements at low pressure (1x10(exp -1) Pa) to investigate the feasibility of LIBS measurement under vacuum conditions. Although the optical emission intensity decreases remarkably at low ambient pressure, our experimental results indicate that the precision of elemental abundance measurements does not decrease drastically even at 1x10(exp -1) Pa. This suggests that LIBS can be used at the surface of airless bodies, such as the Moon and asteroids., 著者人数: 11人, 形態: カラー図版あり, Number of authors: 11, Physical characteristics: Original contains color illustrations, 資料番号: AA0065116028}, publisher = {宇宙航空研究開発機構宇宙科学研究所 (JAXA)(ISAS), Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)}, title = {Laser-induced breakdown spectroscopy measurement under low pressure simulating vacuum conditions}, volume = {43}, year = {2010} }
