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.

编织是4.2m威廉·赫歇尔望远镜（WHT）的新型广阔的高场，高多重光谱设施的概念。编织将为WHT配备新的介质/高光谱分辨率双光束光谱仪（r = 5000/r = 20000），该光谱仪可从新的2度视图量仪器仪器中提供多达1000个同时的纤维式馈送。相同的光谱仪也可以带有具有3x2 Arcminute视野的大型基基整体场单元（IFU），或最多30个小型，可部署的IFU，每个IFU，每个IFU，每个IFU都有一个10x12 Arcsecond的视野。编织的主要科学目标是Gaia目录的光谱随访，以在微弱的幅度和较大的径向距离下对银河系的动力学和化学演化进行采样。使用在Westerbork的Apertif仪器中从Apertif仪器中观察到的互补的中性氢观察的可分辨的运动学研究，以适度的红移（Z <0.4）研究星系进化，并研究宇宙的大型宇宙结构的进化，并通过封装了深度范围的无线电范围，并测试了深度范围的无线电范围的范围。牛津在编织初步设计阶段的纤维定位系统上的工作是开发完整的定位器概念以及位置器系统和望远镜顶端环结构之间的接口。
