Issue Date: | 2018 | Volume: | Ground-based and Airborne Instrumentation for Astronomy VII | Editors: | Evans, Christopher J.; Simard, Luc; Takami, Hideki | Series: | PROCEEDINGS OF SPIE | Number: | 10702 | First Page: | 107021B | Abstract: | We present an update on the overall construction progress of the WEAVE next-generation spectroscopy facility for the William Herschel Telescope (WHT), now that all the major fabrication contracts are in place. We also present a summary of the current planning behind the 5-year initial phase of survey operations, and some detailed end-to-end science simulations that have been effected to evaluate the final on-sky performance after data processing. WEAVE will provide optical ground-based follow up of ground-based (LOFAR) and space-based (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, 20 integral field units, or a single large IFU for each observation. The fibres are fed to a single (dual-beam) spectrograph, with total of 16k spectral pixels, 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. The project has experienced some delays in procurement and now has first light expected for the middle of 2019. | Conference Name: | Ground-based and Airborne Instrumentation for Astronomy VII | Conference Place: | Austin, Texas, United States | Conference Date: | 10-15 June, 2018 | URI: | http://hdl.handle.net/20.500.12386/28166 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10702/2312031/Construction-progress-of-WEAVE--the-next-generation-wide-field/10.1117/12.2312031.short?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781510619586 | DOI: | 10.1117/12.2312031 | Bibcode ADS: | 2018SPIE10702E..1BD | Fulltext: | open |
