This project will develop a new multi-user multi-institutional research instrument -- a magnetized dusty plasma device. The device would be housed at Auburn University (Auburn, Alabama). The PI (Edward Thomas, African American) from Auburn University, heads a strong team of co-PIs including Marlene Rosenberg (female) from University of California, San Diego, and Robert Merlino from the University of Iowa (EPSCoR state). This project combines the integrated development of a superconducting, high magnetic field (|B| = 4 Tesla) system, a flexible, multiconfiguration plasma chamber and plasma source, a novel nanoparticle imaging system, and an advanced, network-based control system to create a unique, research device that will be the premier instrument of its type in the dusty plasma research community. This project is the culmination of over two years of international development activity. This effort has leveraged the expertise of the entire dusty plasma research community as well as involving researchers with interests in fusion, astrophysics, and fluid mechanics, and thus provides strong evidence that this community will embrace this project and make use of this new resource. Moreover, this proposed project is transformational in that, once operational, this device will allow access to regimes of dusty plasma behavior that have previously been inaccessible, which provides additional motivation for broad community support for this project. Investigations of grain charging (e.g., ion/electron gyro-orbits less than inter-grain distances), wave phenomena (e.g., electrostatic dust cyclotron wave), magnetic field effects on dust transport (e.g., g[vector] ×B[vector] drift), and the behavior of plasma with embedded paramagnetic particles are new scientific topics that will be enabled by this device.

该项目将开发一种新的多用户多机构研究仪器----磁化尘埃等离子体装置。该设备将被安置在奥本大学（奥本，亚拉巴马）。来自奥本大学的PI（Edward托马斯，非裔美国人）领导着一个强大的联合PI团队，其中包括来自加州大学圣地亚哥分校的Marlene Rosenberg（女）和来自爱荷华州大学（EPSCoR州）的Robert梅尔利诺。 该项目结合超导、高磁场（|B| = 4特斯拉）系统，一个灵活的，多配置的等离子体室和等离子体源，一种新型的纳米粒子成像系统，和一个先进的，基于网络的控制系统，以创建一个独特的，研究设备，将是其类型的首要仪器在尘埃等离子体研究社区。该项目是两年多国际发展活动的成果。这项工作利用了整个尘埃等离子体研究界的专业知识，并涉及对聚变，天体物理学和流体力学感兴趣的研究人员，从而提供了强有力的证据，表明该社区将接受这一项目并利用这一新资源。此外，这个拟议的项目是转型的，因为一旦投入使用，这个设备将允许访问以前无法访问的尘埃等离子体行为的制度，这为广泛的社区支持这个项目提供了额外的动力。谷物装料的调查（例如，离子/电子回转轨道小于晶粒间距离），波动现象（例如，静电尘埃回旋波）、磁场对尘埃传输的影响（例如，g [矢量] × B [矢量]漂移），以及嵌有顺磁粒子的等离子体的行为，都是该装置将使能的新的科学课题。
