Development of a Mid-Infrared Astronomical Echelle Spectrometer

建立了用于中红外天文观测的低温梯队光谱仪。它已被证明是一种极其灵敏的仪器，能够进行各种各样的天文观测。光谱仪沿着一条投射到天空上的狭缝观察10个位置，采样64个光谱点，分辨率在1000到30000之间。该光谱仪将通过修复几个已知的问题，扩展其功能，并使其能够为更广泛的用户使用来改进。具体计划项目包括：扩大可观测波长范围至20um区域，购置备用数据采集设备，改进数据采集和分析软件，研究红外发光星系和星际分子。

A cryogenic echelle spectrometer has been constructed for mid- infrared astronomical observations. It has been shown to be an extremely sensitive instrument, capable of a wide variety of astronomical observations. The spectrometer observes ten positions along a slit projected onto the sky, sampling 64 spectral points with resolving power between 1000 and 30,000. This spectrometer will be improved by fixing several known problems, expanding its capabilities, and making it accessible to a wider range of users. Specific projects planned included: expanding the wavelength range observable to include the 20um region, acquisition of backup data acquisition equipment, improvement of data acquisition and analysis software, and study of infrared luminous galaxies and interstellar molecules.
