In a dusty plasma, the usual ion-electron-neutral plasma is modified by the presence of a third charged species, charged microparticles or "dust". These microparticles can range in size from tens of nanometers to a few millimeters in diameter and can become very highly charged and form two- and three-dimensional clouds that can modify the bulk properties of the surrounding plasma. This research addresses two aspects of plasma dust clouds, the particle cloud-plasma interface and the thermodynamics of the microparticles. These will be explored using novel microparticle control techniques and a combination of two- and three-dimensional Particle Image Velocimetry (PIV) diagnostic systems

在尘埃等离子体中，通常的离子-电子-中性等离子体被第三种带电物质，带电微粒或“尘埃”的存在所改变。这些微粒的直径可以从几十纳米到几毫米不等，并且可以变得非常带电，形成二维和三维云，可以改变周围等离子体的整体特性。 本研究针对电浆尘埃云的两个方面，粒子云-电浆界面以及微粒的热力学。将使用新型微粒控制技术以及二维和三维粒子图像测速（PIV）诊断系统的组合来探索这些技术
