第25回宇宙利用シンポジウム(2009年1月14日-15日, 宇宙航空研究開発機構宇宙科学研究本部相模原キャンパス), The Twenty-fifth Space Utilization Symposium (January 14-15, 2009: ISAS/JAXA Sagamihara, Japan), The electromagnetic levitator for microgravity condition called PFLEX (Parabolic Flight Levitation Experiment Facility) was improved for precision measurement of surface tension of high temperature melt. We succeeded in the electromagnetic levitation of molten copper during the parabolic flight regardless of the gravitational change from 1.5 G to micro G. Several peaks were observed in the frequency spectrum for the surface oscillation of the molten copper, the spectrum becomes simple under micro G due to the release of the external force from gravitational acceleration and electromagnetic force., 資料番号: AA0064297085
