A Very High Resolution Infrared Astronomical Spectrograph

一台高分辨率（R = 1.2 × 105）中红外光谱仪 天文观测建议。 摄谱仪会 是一个液氦冷却，双通，中阶梯使用40厘米长， 刺耳。 它将能够分辨2.5 km s-1多普勒的谱线 宽度和噪声等效线通量约为4 x 10-14 erg s-1 cm-2（1. 1秒），允许高信噪比观测 许多年轻恒星嵌入在分子云中。 仪器 将主要用于星际分子的研究。 非常 需要高分辨率和高灵敏度观测， 分子云的红外观测，特别是 围绕着年轻的恒星。

A very high resolution (R = 1.2 x 105) mid-infrared spectrograph for astronomical observations is proposed. The spectrograph will be a liquid helium cooled, double-pass, echelle using a 40 cm long grating. It will be able to resolve lines with 2.5 km s-1 Doppler width and will have a noise-equivalent line flux of ~ 4 x 10-14 erg s-1 cm-2 (1. in 1 second), allowing high signal-to-noise observations of many young stars embedded in molecular clouds. The instrument will be used primarily for studies of interstellar molecules. Very high resolution and high sensitivity observations are necessary for infrared observations of molecular clouds, especially the regions around young stars.
