WEAVE is a concept for a new wide-field, high multiplex spectroscopy facility for the 4.2m William Herschel Telescope(WHT). WEAVE will equip the WHT with a new medium/high spectral resolution dual-beam optical spectrograph (R=5000/R=20000) that will be fed with up to 1000 simultaneous fibre-optic feeds from a new 2 degree field of view prime-focus instrument. The same spectrograph can also be fed with a large single fibre-based integral field unit (IFU) with a 3x2 arcminute field of view, or with up to 30 small, individually deployable IFUs, each with a 10x12 arcsecond field of view. The main scientific objectives for WEAVE are spectroscopic follow-up of the GAIA catalogue to sample the dynamics and chemical evolution of the Milky Way at faint magnitudes and large radial distances; to study galaxy evolution at modest redshifts (z<0.4) using resolved kinematics of up to 100,000 galaxies with complementary neutral hydrogen observations from the APERTIF instrument at Westerbork, and to study the evolution of the large-scale structure of the Universe and test theories of Dark Energy by means of follow-up observations of the LOFAR medium deep wide-field radio imaging survey.This proposal covers the initial phase of Oxford's work on the fibre positioning system for the Preliminary Design Phase of WEAVE with the primary objective of developing the complete positioner concept and the interfaces between the positioner system and the telescope top-end ring structure.

WEAVE 是用于 4.2m 威廉·赫歇尔望远镜 (WHT) 的新型宽视场、高多重光谱设施的概念。 WEAVE 将为 WHT 配备新型中/高光谱分辨率双光束光学摄谱仪 (R=5000/R=20000)，该摄谱仪将从新的 2 度视场中同时接收多达 1000 个光纤信号。聚焦仪器。同一摄谱仪还可以配备具有 3x2 角分视场的大型单光纤积分现场单元 (IFU)，或最多 30 个小型、可单独部署的 IFU，每个 IFU 具有 10x12 角秒视场。 WEAVE 的主要科学目标是对 GAIA 星表进行光谱跟踪，以在微弱星等和大径向距离下对银河系的动力学和化学演化进行采样；使用多达 100,000 个星系的解析运动学以及来自 Westerbork 的 APERTIF 仪器的互补中性氢观测来研究适度红移（z<0.4）下的星系演化，并研究宇宙大尺度结构的演化并测试宇宙的理论暗能量通过 LOFAR 中深广域射电成像勘测的后续观测来实现。该提案涵盖了牛津大学光纤定位系统工作的初始阶段WEAVE 的初步设计阶段，主要目标是开发完整的定位器概念以及定位器系统和望远镜顶端环结构之间的接口。
