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是为4.2米威廉赫歇尔望远镜（WHT）设计的一种新的宽视场、高复用光谱设备的概念。WEAVE将为WHT配备一台新的中/高光谱分辨率双光束光谱仪（R=5000/R=20000），该光谱仪将从一台新的2度视场主聚焦仪器同时提供多达1000个光纤。同一台光谱仪还可以配备一个具有3x 2弧分视场的大型单光纤积分场单元（IFU），或者配备多达30个小型可单独部署的IFU，每个IFU的视场为10 x12弧秒。WEAVE的主要科学目标是对GAIA目录进行光谱跟踪，以在微弱的星等和较大的径向距离上对银河系的动力学和化学演变进行取样;研究星系在适度红移下的演化（z<0.4）利用Westerbork的APERTIF仪器对多达100，000个星系的解析运动学和补充中性氢观测，并通过对LOFAR介质深宽的跟踪观测，研究宇宙大尺度结构的演化，检验暗能量理论，本建议书涵盖了牛津大学在WEAVE初步设计阶段光纤定位系统工作的初始阶段，其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。
