Gemini North & South Receive New Instruments for the Holidays!
December 18, 2002
|Michelle (Gemini North)||GMOS-S (Gemini South)|
|The Gemini Multi-Object Spectrograph (GMOS) at Gemini South
South took delivery of GMOS-S in November 2002 and is preparing to
install it on the telescope for commissioning very early in 2003. It is
anticipated that GMOS-S will be available during semester 2003B in both
imaging and several spectroscopic modes.
Like its twin that began observations in 2001 on Gemini North, GMOS-S was built as a collaboration between Canada (HIA), and the UK (Astronomical Technology Centre at ROE and University of Durham). The GMOS detector system was provided by the US (National Optical Astronomy Observatory). The two GMOSs are the primary instruments for optical (0.36-1.10 µm) slit/multi-slit/integral field spectroscopy as well as imaging (5.5 arcmin field of view) on the Gemini telescopes. Both instruments include a wide assortment of filters and other features that can be found at: http://www.gemini.edu/sciops/instruments/gmos.
|Michelle at Gemini North
facility mid-infrared imager and spectrometer Michelle arrived at
Gemini North in the first week of December, however, Michelle did not
arrive from the institution where it was built (the Astronomy
Technology Center at the Royal Observatory of Edinburgh). Rather, it
arrived from the United Kingdom Infrared Telescope (UKIRT) just 'two
domes down' on the Mauna Kea summit ridge! Gemini and UKIRT have an
agreement that will allow Michelle to be shared between the two
telescope facilities over the course of its lifetime.
brings a new and unique capability to the suite of instruments in the
Gemini North arsenal. Operating at the mid-infrared wavelengths of 5 to
30 microns, Michelle will acquire both images and spectra of celestial
sources. With a start-of-the-art 320x240 BIB detector as its 'eyes'
Michelle will image the skies with 0.1" pixels through a complement of
ten filters that span the 10 and 20 micron atmospheric windows.
Michelle will also produce spectra with resolutions ranging from 200 to
30,000 using 5 different gratings.
currently undergoing a period of engineering and characterization in
the Gemini North pier lab. Testing of the Gemini cryogenic systems and
further testing and optimization of the newly installed detector will
proceed over the holidays. Michelle is scheduled for first scientific
use late in the 2003A semester, in imaging mode only.
