Extreme multiplex spectroscopy at wide-field 4-m telescopes
Robert Content, Tom Shanks
We describe the design and science case for a spectrograph for the prime focus of classical 4-m wide-field telescopes that can deliver at least 4000 MOS slits over a 1 degree field…
Design and construction of the IMACS-IFU, a 2000-element integral field unit
J. Schmoll, G. N. Dodsworth, R. Content +1
The IMACS-IFU is an Integral Field Unit built for the IMACS spectrograph at the Magellan-I-Telescope at Las Campanas Observatory. It consists of two rectangular fields of 5 by 7 ar…
Design of 2-m to 6-m Liquid Mirror Containers
Robert Content
A new design is proposed for large (up to 6-m) liquid mirror containers. The design uses Kevlar, foam and aluminum, as in previous designs, but with a different configuration that…
Mechanical and Thermal Tests of the Containers of Liquid Mirrors
E. F. Borra, R. Content, G. Tremblay +2
We give a generic description of a liquid mirror system and summarize some practical information useful to making them. We compare laboratory measurements of deformations, due to t…
The GMOS integral field unit: first integral field spectroscopy with an 8m telescope
Jeremy Allington-Smith, Graham Murray, Robert Content +8
The Gemini Multiobject Spectrograph (GMOS) installed on the Gemini-North telescope has a facility for integral field spectroscopy over the wavelength range 0.4-1.0um. GMOS is conve…
