Abstract: WEAVE will provide ∼1000 multiplex spectroscopy, fed by a new 2 degree field of view at prime focus on the WHT. The prime focus positioner hosts 2 sets of single-fiber 1.3'' MOS pickoffs, 20 small integral field units (∼ 11'×12''), and a single large, ∼ 1.3' × 1.5' integral field unit. These fiber modes feed a single, dual-beam spectrograph located within the WHT's GHRIL enclosure. The spectrograph provides R=5000 spectroscopy over the full range from 366 nm to 950 nm, or two smaller ranges at R=20000. These modes are fixed. The intention of WEAVE is to operate in survey mode with a number of community-driven projects merged into joint science observations. In this paper I summarize the instrument design and performance parameters.
