暗能量光谱仪器(DESI)正在建设中,它将使用重子声学振荡技术来测量宇宙的膨胀历史。在实验期间,将测量超过14000平方度的3500万个星系和类星体的光谱。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个宽带摄谱仪提供信号。我们将介绍光纤电缆的设计和生产过程,应变缓解系统和狭缝端制备。与以前的项目相比,DESI所需的更大规模的生产需要与工业界合作,找到一个解决方案,以减少生产的时间尺度,并尽量减少对光纤的压力。
The Dark Energy Spectroscopic Instrument (DESI) is under construction to measure the expansion history of the Universe using the Baryonic 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 10 broad-band spectrographs. We will describe the design and production progress on the fibre cables, strain relief system and preparation of the slit end. In contrast to former projects, the larger scale of production required for DESI requires teaming up with industry to find a solution to reduce the time scale of production as well as to minimise the stress on the optical fibres.
