本文针对Spec-S5、MUST和WST等未来多路复用巡天项目对多目标光谱观测的需求,研究了alpha-beta光纤定位器三角模块的焦平面覆盖优化与组装,对比了有框、半无框和全无框三种模块排列方式,并验证了其满足焦平面组装要求的能力。

摘要:

多路复用巡天计划有志于为下一代焦平面仪器扩大规模。Spec-S5、MUST和WST等未来项目对多目标光谱观测(13,000至20,000个同时观测目标)的需求日益增长,这要求对新型焦平面仪器进行深入研究。本文对alpha-beta光纤定位器(6.2 mm间距)三角模块的焦平面覆盖优化和组装进行了严格研究。主要关注点是检验不同的模块排列方式,即有框、半无框和全无框组装。有框和半无框在此描述使用制造好的焦面板将模块固定在一起,并为光纤提供正确的焦距和倾斜度。还将介绍自动生成此类焦面板的工作,以提高项目的适应性和制造便利性。另一方面,无框方法提出了一种无需焦面板的连接方法。本文还将展示它们满足焦平面组装要求(如焦距、倾斜度和覆盖范围)的能力。

英文摘要:

Multiplexed surveys have the ambition to grow larger for the next generation of focal plane instruments. Future projects such as Spec-S5, MUST, and WST have an ever-growing need for multi-object spectroscopy (13,000 - 20,000 simultaneous objects) which demands further investigations of novel focal plane instrumentation. In this paper, we present a rigorous study of focal plane coverage optimization and assembly of triangular modules of alpha-beta fiber positioners with a 6.2 mm pitch. The main focus here is to examine different module arrangements namely, framed, semi-frameless, and fullyframeless assemblies. Framed and semi-frameless describe here the usage of a manufactured focal plate to hold the modules together and provide the correct focus and tilt to the fibers. Work on automatically generating such focal plates for project adaptability and ease of manufacturing will also be presented. On the other hand, the frameless approach proposes a connection method freed from the need of a focal plate. The following paper will also present their capabilities to meet the requirements for focal plane assembly such as focus, tilt and coverage.
