Design evolution for the Wide-field Spectroscopic Telescope
Will Saunders, Corentin Cudennec, Roland Bacon +4
WST is proposed as the next large ESO project to follow ELT, combining Multi-Object Spectroscopy and Integral Field Spectroscopy. Each mode offers order-of-magnitude gains over cur…
The Wide-field Spectroscopic Telescope (WST): design trade-offs for the low-resolution multi-object spectrograph instrument
Dimitri Buffat, Will Saunders, Kjetil Dohlen +10
The Wide-field Spectroscopic Telescope (WST) is a planned 12-meter-class dedicated spectroscopic facility designed to address key scientific challenges through large spectroscopic…
Exploration of small footprint stick-slip piezoelectric actuators for use in the FLEX fibre positioner system for the Wide-field Spectroscopic Telescope (WST)
Joseph W. Barrow, Suryansh Saxena, Jon S. Lawrence +2
This work presents a novel stick-slip piezoelectric actuator for the FLEX fibre positioner, addressing the challenge of reducing footprint while maintaining precision in next-gener…
WST -- Wide-field Spectroscopic Telescope: The Next Leap in Wide-field Spectroscopy
Roland Bacon, Olga Bellido, Philippe Dierickx +53
The Wide-field Spectroscopic Telescope (WST) is a concept for a dedicated 12-m spectroscopic survey facility designed to address some of the most important questions in astrophysic…
The Wide-field Spectroscopic Telescope: optical designs for the low-resolution multi-object spectrographs
Will Saunders, Kjetil Dohlen, Dimitri Buffat +7
In MOS Low-Resolution mode, WST has a 'spectral etendue' per fiber (etendue x spectral resolution elements) twice as large as any existing MOS instrument, and a total spectral eten…
WST, the wide-field spectroscopic telescope: progress on the design of the instruments
David Lee, Joel Vernet, Elizabeth George +47
WST, the Wide-field Spectroscopic Telescope is a proposed new facility that will provide a transformational gain in spectroscopic survey capability over existing facilities. The WS…
