AI总结:

本文介绍了DESI光纤系统在Mayall望远镜上的开发、交付与安装过程,该系统利用5000个光纤定位器和十个光谱仪测量数千万星系与类星体光谱以研究宇宙膨胀历史。

摘要:

最近投入使用的Dark Energy Spectroscopic Instrument(DESI)将利用重子声学振荡技术测量宇宙的膨胀历史。在实验期间,将测量覆盖14000平方度天区的3500万个星系和类星体的光谱。为KPNO Mayall望远镜配备的新主焦点改正镜将光线传输至5000个光纤定位器。这些光纤进而馈入十个宽带光谱仪。我们描述了Mayall望远镜光纤系统在开发、交付和安装过程中的关键方面及经验教训。

英文摘要:

The recently commissioned Dark Energy Spectroscopic Instrument (DESI) will measure the expansion historyof the universe using the Baryon Acoustic Oscillation technique. The spectra of 35 million galaxies and quasarsover 14000 sq deg will be measured during the life of the experiment. A new prime focus corrector for theKPNO Mayall telescope delivers light to 5000 fiber optic positioners. The fibers in turn feed ten broad-bandspectrographs. We describe key aspects and lessons learned from the development, delivery and installation ofthe fiber system at the Mayall telescope.
