This MRI proposal provides funding for the purchase of a three-dimensial particle imaging velocimetry (PIV) device to augment the existing equipment at the Auburn University Plasma Science Laboratory (PSL). The PSL has a unique niche in the dusty plasma community - the ability to perform real-time, two-dimensional particle transport investigations. This new device makes it possible to overcome the key limitation of the present PIV device, that it is only able to measure two of the three velocity components of the particles. Because dusty plasmas, plasmas containing charged microparticles, are present in many different environments, from astrophysical systems such as nebula and planetary rings to industrial processing tools, understanding the behavior of dusty plasmas in detail will have broad impact in a number of fields.

该 MRI 提案为购买三维粒子成像测速 (PIV) 设备提供资金，以增强奥本大学等离子体科学实验室 (PSL) 的现有设备。 PSL 在尘埃等离子体领域拥有独特的优势——能够进行实时、二维粒子传输研究。 这种新设备可以克服现有 PIV 设备的关键限制，即它只能测量粒子的三个速度分量中的两个。 由于尘埃等离子体（含有带电微粒的等离子体）存在于许多不同的环境中，从星云和行星环等天体物理系统到工业加工工具，详细了解尘埃等离子体的行为将在许多领域产生广泛的影响。
