MRI: Acquisition of an Imaging Spectrograph for High Resolution Spectroscopic Analysis of Discharge Plasmas

这台可用于探索放电等离子体物理特性的高分辨率光谱仪的获得，将推动威廉·帕特森大学和史蒂文斯理工学院的研究活动。摄谱仪分析光源或放电等离子体发出的光强度作为波长的函数，波长可用于表征光源，从而更好地理解放电中发生的物理过程。在涉及高压等离子体的光源中，相关信息包括旋转、振动和电子温度、电子密度以及在放电中发生的碰撞和辐射过程。这些结果可以用来模拟在放电过程中发生的过程，并确定等离子体处于热平衡的程度。许多涉及高压等离子体的有趣应用包括准分子灯，高功率激光器，打开开关和新型等离子体处理应用。该仪器为威廉帕特森大学和更广泛的社区提供了前沿研究的机会。更广泛的社区包括来自经济困难背景的高中生，本科生和来自其他机构的研究生。对这些人群的影响包括让更多的观众接受尖端研究工具的培训，反过来，这可能使学生更有可能继续接受更高水平的物理科学教育。此次收购将促进威廉帕特森大学和史蒂文斯理工学院之间跨越化学、物理和化学工程学科的合作研究环境。

The acquisition of this high-resolution spectrograph that can be used to explore the physical properties of discharge plasmas will advance research activities at William Paterson University and Stevens Institute of Technology. A spectrograph analyzes the intensity of light emitted by a light source or discharge plasma as a function of wavelength that can be used to characterize the light source, leading to greater understanding of the physical processes that occur in the discharge. In light sources that involve high-pressure plasmas the pertinent information includes the rotational, vibrational and electronic temperatures, the electron density and the collisional and radiative processes occurring in the discharge. These results can be used to model the processes occurring in the discharge and determine the extent in which the plasmas are in thermal equilibrium. The many interesting applications that involve high-pressure plasmas include excimer lamps, high power lasers, opening switches, and novel plasma processing applications. This instrument provides opportunities in cutting edge research at William Paterson University and also for a broader community. The broader community includes high school students from economically disadvantaged backgrounds, undergraduate students and graduate students from other institutions. The impact on these populations includes exposing a larger audience to training on a cutting edge research instrument that, in turn, may make the students more likely to go on to higher levels of education in the physical sciences. The acquisition will foster a collaborative research environment that will extend across the disciplines of chemistry, physics and chemical engineering and between William Paterson University and Stevens Institute of Technology.
