Short duration microgravity experiments are useful tools for the development of experimental apparatus for microgravity researches. Parabolic flights have been frequently used for the development of the electrostatic levitation furnace (ELF) for the International Space Station (ISS). The history of ELF development and parabolic flight experiments conducted for its development are briefly described in this paper., 形態: 図版あり, Physical characteristics: Original contains illustrations, 資料番号: DS1440102000

高温融体内の原子の運動に関する実験的な知見は、融体の熱物性と構造の関係を理解する上で極めて重要である。我々は、高温融液の原子ダイナミクスの観察を目的として非弾性X線散乱用の小型の静電浮遊装置を開発し、融点および過冷却液体シリコンの動的構造因子を測定した。本装置を用いることにより液体シリコンのフォノンピークが明瞭に観察され、その分散関係が明らかになった。, The atomic dynamics in high temperature melts are essential information for the understanding of the relation between liquid structure and thermo-physical properties in liquid state. The small Electrostatic Levitation furnace, ESL, was developed for the inelastic X-ray scattering facility in SPring-8. The observation of dynamic liquid structure factor, S (Q, w) of normal and undercooled liquid silicon was performed. The phonon peak of S (Q, w) in the liquid silicon was clearly observed and its dispersion relation can be obtained., 資料番号: AA0063323004, レポート番号: JAXA-RR-06-015E

The Electrostatic Levitation Furnace (ELF) is one of the experiment facilities for materials science, which will be on board Japanese Experiment Module “Kibo” of the International Space Station (ISS) in 2015. Since JAXA decided twenty years ago that ISS levitation furnace control method should be Coulomb force, we continued further research experiments and development of ground models. In 2011, JAXA has proceeded to the development phase of ELF and we are now ready to finish the development of ELF. JAXA plans to study thermophysical properties of many kinds of the oxides which cannot be measured on earth. In addition, creation of new materials is another objective of space experiments using ELF. Both is expected to contribute to a new discovery of scientific research and industrial applications. This paper shows the overview of ELF including the history of design concept., Accepted: 2015-01-19, 資料番号: PA1510046000
