论文摘要
灰尘等离子体中灰尘合奏的温度是其最基本的特性之一。在这里，我们提出了使用构型温度作为用于尘土飞扬的温度分析的实验。使用粒子相互作用的模型，构型温度使我们能够通过测量粒子位置而不是粒子速度来确定灰尘集合的温度。将提出基本概念，并将该技术应用于二维有限簇以及来自扩展的尘埃云中的三维数据。另外，构型温度可用于从与标准动力学温度的比较中得出粒子电荷和筛选长度。
The temperature of a dust ensemble in a dusty plasma is one of its most fundamental properties. Here, we present experiments using the configurational temperature as a for the temperature analysis in dusty plasmas. Using a model of the particle interactions, the configurational temperature allows us to determine the temperature of the dust ensemble from measurements of the particle positions, rather than particle velocities. The basic concept will be presented and the technique is applied to two-dimensional finite clusters as well as three-dimensional data from an extended dust cloud. Additionally, the configurational temperature can be used to derive the particle charge and the screening length from a comparison with the standard kinetic temperature.
