暗能量光谱仪器(DESI)正在建设中,使用重子声学振荡技术来测量宇宙的膨胀历史。超过14000平方公里的3500万个星系和类星体的光谱。度将在实验期间测量。KPNO Mayall望远镜的新型定焦校正器将向5000个光纤定位器提供光。这些纤维依次为10个宽带摄谱仪供能。我们描述了DESI狭缝组件的设计、生产、质量保证程序和性能。
The Dark Energy Spectroscopic Instrument (DESI) is under construction to measure the expansion history of the Universe using the Baryon Acoustic Oscillation technique. The spectra of 35 million galaxies and quasars over 14000 sq. deg will be measured during the life of the experiment. A new prime focus corrector for the KPNO Mayall telescope will deliver light to 5000 fibre optic positioners. The fibres in turn feed ten broad-band spectrographs. We describe the design, production, quality assurance procedures and performance of the DESI slit assemblies.
