HIRDES -世界空间天文台紫外线（WSO/UV）的高分辨率双阶梯摄谱仪
HIRDES - The High-Resolution Double-Echelle Spectrograph for the World Space Observatory Ultraviolet (WSO/UV)
摘要：
世界空间紫外线观测站（WSO/UV）是一个多国项目，它是出于天文学界对未来进入紫外线范围的需要而发展起来的。WSO/UV由一个单一的紫外望远镜组成，其主镜直径为1.7米，为紫外光谱仪和紫外成像仪供电。光谱仪包括三个不同的光谱仪，两个高分辨率阶梯光栅光谱仪（高分辨率双阶梯光栅光谱仪，HIRDES）和一个低色散长缝仪器。在HIRDES中，102- 310 nm的光谱带被分离，以提供两个中阶梯光谱仪，覆盖紫外范围174- 310 nm和真空紫外范围102- 176 nm，具有高光谱分辨率（R> 50，000）。技术概念是基于前两次ORFEUS SPAS任务的遗产。本文描述了B1阶段的开发活动，考虑到性能方面，设计驱动因素，相关的权衡（机械概念，材料选择等）。以及关键功能和环境测试验证方法。本文还介绍了世界天文台其他紫外科学仪器（成像仪）的现状。
英文摘要：
The World Space Observatory Ultraviolet (WSO/UV) is a multi-national project grown out of the needs of the astronomical community to have future access to the UV range. WSO/UV consists of a single UV telescope with a primary mirror of 1.7m diameter feeding the UV spectrometer and UV imagers. The spectrometer comprises three different spectrographs, two high-resolution echelle spectrographs (the High-Resolution Double-Echelle Spectrograph, HIRDES) and a low-dispersion long-slit instrument. Within HIRDES the 102-310nm spectral band is split to feed two echelle spectrographs covering the UV range 174-310nm and the vacuum-UV range 102-176nm with high spectral resolution (R>50,000). The technical concept is based on the heritage of two previous ORFEUS SPAS missions. The phase-B1 development activities are described in this paper considering performance aspects, design drivers, related trade-offs (mechanical concepts, material selection etc.) and a critical functional and environmental test verification approach. The current state of other WSO/UV scientific instruments (imagers) is also described.
