我们提出了威廉·赫歇尔望远镜（WHT）的WEAVE下一代光谱设施的初步设计，主要针对即将到来的地基（LOFAR）和天基（盖亚）调查的光学地面跟踪。WEAVE是一个多目标和多IFU设施，在WHT上使用新的2度主聚焦视场，缓冲拾取和放置定位器系统托管1000个多目标（MOS）光纤或每次观察最多30个积分场单元。光纤被馈送到单个光谱仪，具有一对8 k（光谱）x 6 k（空间）像素的相机，位于望远镜Nasmyth平台上的WHT GHRIL外壳内，支持在R~5000下在单次曝光中在整个370- 1000 nm波长范围内的观测，或者在R~20000下每个臂中具有有限覆盖范围的高分辨率模式。
We present the preliminary design of the WEAVE next generation spectroscopy facility for the William Herschel Telescope (WHT), principally targeting optical ground-based follow up of upcoming ground-based (LOFAR) and spacebased (Gaia) surveys. WEAVE is a multi-object and multi-IFU facility utilizing a new 2 degree prime focus field of view at the WHT, with a buffered pick and place positioner system hosting 1000 multi-object (MOS) fibres or up to 30 integral field units for each observation. The fibres are fed to a single spectrograph, with a pair of 8k(spectral) x 6k (spatial) pixel cameras, located within the WHT GHRIL enclosure on the telescope Nasmyth platform, supporting observations at R~5000 over the full 370-1000nm wavelength range in a single exposure, or a high resolution mode with limited coverage in each arm at R~20000.
