 note = {The fine particle (dusty) plasma is a charge-neutral mixture of micron-sized fine (dust) particles and ambient plasma composed of ions and electrons. Typical densities of fine particles and ambient plasma are (10(exp 4) ～ 10(exp 5)) cm(exp -3) and (10(exp 6) ～ 10(exp 8)) cm(exp -3), respectively. Images of fine particles are easily captured and identified by CCD cameras through the scattering of the laser beam and we are able to make particle level observations. In contrast to singly charged ions or electrons, fine particles in plasmas have large negative charges up to 10(exp 3) or even 10(exp 4) times as large as that of an electron, enabling observations of various effects coming from the strong Coulomb coupling between fine particles. For this reason, a lot of researches on fine particle plasmas have been performed recently. One of the most Interesting phenomena in strongly coupled systems may be the ones related to the critical point. In this report, we give a summary of our proposal to observe critical phenomena in fine particle plasmas in PK-3PLUS under the condition of the microgravity and the present status of data analysis. In PartⅠ, the theoretical background is given and the possibility to observe the critical point is shown with an emphasis on the differences between the simple one-component plasma (OCP) model of the charged particle systems and systems with the background as real physical entity. In Part II, characteristic parameters realized in PK-3 PLUS are analyzed in relation to those of the critical point. The behavior of the structure factor is discussed in comparison with the effects of inhomogeneity and finiteness of observed samples and conclusions are given., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1530015003, レポート番号: JAXA-RR-14-012E},
