Descripción
WEAVE is the next-generation wide-field optical spectroscopy facility
for the William Herschel Telescope (WHT) on La Palma in the Canary
Islands, Spain. It is a multi-object "pick-and-place" fibre-fed
spectrograph with a 1000 fibre multiplex behind a new dedicated 2°
prime focus corrector. The WEAVE positioner concept uses two robots
working in tandem in order to reconfigure a fully populated field within
the expected 1 hour dwell-time for the instrument (a good match between
the required exposure times and the limit of validity for a given
configuration due to the effects of differential refraction). In this
paper we describe some of the final design decisions arising from the
prototyping phase of the instrument design and provide an update on the
current manufacturing status of the fibre positioner system.
