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工具，这是一种磁性灰尘等离子体设备。该设备将安置在奥本大学（阿拉巴马州奥本）。来自奥本大学的PI（爱德华·托马斯（Edward Thomas），非裔美国人）领导着一支由加利福尼亚大学，圣地亚哥分校的玛琳·罗森伯格（Marlene Rosenberg）组成的强大团队，以及爱荷华大学（Epscor）州立大学的罗伯特·梅利诺（Robert Merlino）。该项目结合了超导，高磁场（| b | = 4 Tesla）系统的集成开发，一种灵活的，多浓度的等离子体室和等离子体来源，一种新型的纳米粒子成像系统，以及一个先进的基于网络的控制系统，以创建独特的研究设备，是其在尘埃盆栽群体中类型的主要工具。该项目是两年以上国际发展活动的高潮。这项努力利用了整个尘土飞扬的等离子体研究社区的专业知识，并吸引了对融合，天体物理学和流体机制感兴趣的研究人员，因此提供了有力的证据，表明该社区将接受该项目并利用这一新资源。此外，该提议的项目具有变革性，一旦运行，该设备将允许访问以前无法访问的尘土飞扬行为的制度，这为该项目提供了广泛的社区支持，这为该项目提供了更多动力。研究谷物充电（例如，离子/电子陀螺仪小于粒间距离），波浪现象（例如，静电粉尘循环率波），磁场对粉尘传输的影响（例如，G [vector]×B [vector]×b [vector]漂移）以及通过胚胎的启动式的paragagnexicic paremics oticic pomicic pomicic pomicic parsicic pomicic potics werticic pomicic with sipictic pomicic pomicic with sicordic with sicordic。
