WEAVE Spectrograph Final Design Review

Submitter: Johan Pragt
Description: WEAVE is a new multi-object survey spectrograph for the 4.2-m William Herschel Telescope (WHT) at the Observatorio del Roque de los Muchachos, on La Palma in the Canary Islands. It will allow astronomers to take optical spectra of up to ~1000 targets over a two-degree field of view in a single exposure (MOS), or to carry out integral-field spectroscopy using 20 deployable mini integral-field units (mIFUs) or one large fixed integral-field unit (LIFU). WEAVE's fibre-fed spectrograph comprises two arms, one optimised for the blue and one for the red, and offers two possible spectroscopic resolutions, 5000 and 20,000.

The principal science goals are twofold:
  • Milky Way archaeology: exploiting Gaia's scientific legacy.
  • Galaxy evolution and cosmology: exploiting SKA Pathfinders (e.g. LOFAR and APERTIF on the WSRT).

    The Final Design Review of the Spectrograph of WEAVE took place last 17 and 18 March at ASTRON. The team successfully passed this important milestone. The picture shows the Review Board, the WEAVE management team and the Spectrograph team in the backyard of ASTRON.

    The Spectrograph team is a collaboration between NOVA Optical IR Instrumentation Group at ASTRON (Optomechanical Design and Production, Management), RAL in the UK (Optical Design), JMU Liverpool in the UK (Detectors), IAC at Tenerife Spain (Control Hardware), ING at La Palma Spain (Control Software), INAF Italy (VPH Gratings and Control Software). Dutch PI is Scott Trager, Kapteyn Astronomical Institute, RUG.
