Upgrade of the Steward Observatory Cryogenic Spectrometer

小行星9315872 低温光谱仪的开发于1989年由美国国家科学基金会资助。 当时，该文书包括关于提高能力的规定，现在正在实施。 这些能力包括从大约700或3,700（取决于光栅）增加到大约19000的分辨率。 一个现有的倾斜/倾斜镜系统也将适应于仪器，以提高有效的灵敏度，稳定星星图像的仪器狭缝。 升级的分辨率是由一种新的浸没式硅中阶梯光栅完成的。 与其他天文台的设施仪器相比，该仪器的新颖设计以相对较低的成本提供了新的功能。 光谱仪将与斯图尔特天文台的望远镜以及升级后的6.5米多镜望远镜一起使用。 ***

9315872 Rieke Development of the cryogenic spectrometer was funded by the National Science Foundation in 1989. At that time the instrument included provision for upgraded capabilities which are now to be implemented. These capabilities include increased resolution from approximately 700, or 3,700 depending upon the grating, to approximately 19,000. An existing tip/tilt mirror system will also be adapted to the instrument to improve the effective sensitivity by stabilizing star images on the instrument slit. The upgraded resolution is to be accomplished with a new immersed-silicon echelle grating. The novel design of the instrument provides the new capabilities at relatively low cost in comparison with facility instruments at other observatories. The spectrometer will be used with the telescopes of the Steward Observatory as well as with the upgraded 6.5 meter Multiple Mirror Telescope. ***
