FLAMINGOS-2: The Facility Near-Infrared Wide-field Imager & Multi-Object Spectrograph for Gemini
We report on the design and status of the FLAMINGOS-2 instrument - a
fully-cryogenic facility near-infrared imager and multi-object spectrograph for
the Gemini 8-meter telescopes. FLAMINGOS-2 has a refractive all-spherical
optical system providing 0.18-arcsecond pixels and a 6.2-arcminute circular
field-of-view on a 2048x2048-pixel HAWAII-2 0.9-2.4 mm detector array. A
slit/decker wheel mechanism allows the selection of up to 9 multi-object
laser-machined plates or 3 long slits for spectroscopy over a 6x2-arcminute
field of view, and selectable grisms provide resolutions from 1300 to
3000 over the entire spectrograph bandpass. FLAMINGOS-2 is also
compatible with the Gemini Multi-Conjugate Adaptive Optics system, providing
multi-object spectroscopic capabilities over a 3x1-arcminute field with high
spatial resolution (0.09-arcsec/pixel). We review the designs of optical,
mechanical, electronics, software, and On-Instrument WaveFront Sensor
subsystems. We also present the current status of the project, currently in
final testing in mid-2006.Comment: Submitted to SPIE Astronomical Telescopes & Instrumentation; 12

Tcl/Tk in a Nutshell
The Tcl language and Tk graphical toolkit are powerful building blocks for custom applications. This quick reference briefly describes every command and option in the core Tcl/Tk distribution, as well as the most popular extensions. Keep it on your desk as you write scripts, and you'll be able to quickly find the particular option you need
Fisica: The Florida Image Slicer For Infrared Cosmology &Amp; Astrophysics
We report on the design and status of the Florida Image Slicer for Infrared Cosmology and Astrophysics (FISICA) - a fully-cryogenic all-reflective image-slicing integral field unit for the FLAMINGOS near-infrared spectrograph. Designed to accept input beams near f/15, FISICA with FLAMINGOS provides R∼1300 spectra over a 16x33-arcsec field-of-view on the Cassegrain f/15 focus of the KPNO 4-meter telescope, or a 6x12-arcsec field-of-view on the Nasmyth or Bent Cassegrain foci of the Gran Telescopio Canarias 10.4-meter telescope. FISICA accomplishes this using three sets of monolithic powered mirror arrays, each with 22 mirrored surfaces cut into a single piece of aluminum. We review the optical and opto-mechanical design and fabrication of FISICA, as well as laboratory test results for FISICA integrated with the FLAMINGOS instrument. We also discuss plans for first-light observations on the KPNO 4-meter telescope in July 2004
