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.

购买这款可用于探索放电等离子体物理特性的高分辨率摄谱仪将推进威廉帕特森大学和史蒂文斯理工学院的研究活动。 光谱仪分析光源或放电等离子体发射的光强度作为波长的函数，可用于表征光源，从而更好地了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、电子密度以及放电中发生的碰撞和辐射过程。这些结果可用于模拟放电中发生的过程并确定等离子体处于热平衡的程度。涉及高压等离子体的许多有趣的应用包括准分子灯、高功率激光器、打开开关和新颖的等离子体处理应用。 该工具为威廉帕特森大学以及更广泛的社区提供了前沿研究的机会。 更广泛的群体包括经济困难的高中生、其他院校的本科生和研究生。 对这些人群的影响包括让更多的受众接受尖端研究仪器的培训，这反过来又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化学、物理和化学工程学科的合作研究环境。
