WEAVE for the William Herschel Telescope at La Palma
| Submitter: | Johan Pragt |
| Description: | WEAVE is a powerful new multi-object spectrograph that is being planned for the 4.2-m William Herschel Telescope on La Palma in the Canary Islands. It will allow astronomers to take spectra of up to 1000 stars and galaxies in a single exposure. The principal science goals are twofold: The WEAVE consortium has finished the Phase B of this wide-field (2 degrees), high-multiplex (1000 fibres) spectroscopic survey facility. Today, the Preliminary Design Review will take place In Madrid. The plan is to operate WEAVE on the telescope for several years, yielding spectra (lambda=370-1000 nm) at resolutions R~5000 and R~20,000. The Dutch contribution is the development of 2 of the 3 main units: the Wide Field Corrector and ADC, and the fibre-fed Spectrograph. The work is done in cooperation with several institutes like RAL near Oxford, JMU in Liverpool, and Rijksuniversiteit Groningen. The third main unit of the instrument is the fibre positioner, done by Oxford e.a.. The picture shows the WHT, and a sketch of the wide-field corrector and spectrograph. http://www.ing.iac.es/weave/index.html |
