This CAREER award supports establishment of the Bryn Mawr Plasma Laboratory that has the dual goal of expanding small scale experimental research into the physics of a turbulent plasma, a gas of electrically charged particles, and serving as a gateway for increasing the number of women plasma physicists entering the field. The laboratory has been constructed at Bryn Mawr College, one of the few remaining women's liberal-arts colleges in the nation. It centers around a plasma wind-tunnel experiment in which turbulent plasma is generated and launched down a cylindrical column. Measurements of this plasma will be used to better understand the characteristics of plasma turbulence and to compare it to conventional fluid and air turbulence. The project will also benefit our understanding of plasmas observed in space, such as the solar wind launched by the sun into the solar system, and will help improve prediction of space weather here on Earth. A coaxial plasma gun will be used to generate a stream of magnetized plasma structures called spheromaks down a vacuum chamber, which then evolve via turbulent fluctuations toward relaxation into a Taylor state. High spatial resolution of access ports along the chamber will allow for many simultaneous direct measurements of fluctuating fields, flows, plasma density and temperature. Experimental goals include evaluation and study of the turbulence that is generated as well as establishing this flowing turbulent plasma as an environment in which to study other phenomena - much like the flowing air in a conventional wind-tunnel is used to study aerodynamics. Plans include observations of changes in turbulence in the presence of magnetic dipoles or insulating obstacles, as well as modifications due to injection of energetic particles or waves. Within a controllable laboratory setting, the program seeks to better understand the state of plasma that is observed throughout the solar system - magnetized, turbulent, and fully three-dimensional. Comparisons of this system will be made to data from major spacecraft-based endeavors including the Magnetospheric Multiscale Mission in orbit within Earth's magnetosphere, and the Parker Solar Probe, examining the plasma at the origin of the solar wind itself.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个职业奖支持布林莫尔等离子体实验室的建立，该实验室的双重目标是将小规模实验研究扩展到湍流等离子体（一种带电粒子气体）的物理学，并作为增加女性等离子体物理学家进入该领域的人数的门户。这个实验室建在布林莫尔学院，这是美国仅存的几所女子文科学院之一。它围绕着一个等离子体风洞实验，在这个实验中，湍流等离子体被产生并沿着一个圆柱发射。这种等离子体的测量将用于更好地了解等离子体湍流的特性，并将其与传统的流体和空气湍流进行比较。 该项目还将有助于我们了解在太空中观测到的等离子体，例如由太阳发射到太阳系的太阳风，并将有助于改善对地球上空间天气的预测。同轴等离子体枪将被用来产生一个磁化等离子体结构的流称为spheromaks下的真空室，然后演变通过湍流波动朝着松弛到泰勒状态。沿着腔室的高空间分辨率的进入端口将允许对波动场、流动、等离子体密度和温度进行许多同时的直接测量。实验目标包括评估和研究产生的湍流，以及建立这种流动的湍流等离子体作为研究其他现象的环境-就像传统风洞中的流动空气用于研究空气动力学一样。计划包括在磁偶极子或绝缘障碍物存在的情况下观测湍流的变化，以及由于注入高能粒子或波而引起的变化。在可控的实验室环境中，该计划旨在更好地了解整个太阳系中观察到的等离子体状态-磁化，湍流和完全三维。该系统将与主要航天器的数据进行比较，包括在地球磁层轨道上的磁层多尺度使命，以及帕克太阳探测器，检查太阳风本身起源处的等离子体。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
