== Overview ==

The Goddard-IRAM Superconducting 2mm Observer (GISMO) is a bolometer camera for the IRAM 30m telescope. It has been build by Goddard Space Flight Center, in Greenbelt, Maryland under the lead of Johannes Staguhn. GISMO consists of '''8x16 pixels''' with super conducting transition edge sensors (TES). The TES are read out by time domain SQUID multiplexers built at the National Institute for Standards (NIST), in Boulder, Colorado. . The nominal bandwidth is 140-162GHz (FWHM), pixels are spaced by '''13.75"''', the telescope HPBW is '''16.7"'''. The sensitivity is '''16 mJy sqrt(sec)''' per beam. The field-of-view is 1.8'x3.7'. In the standard observing mode, data are taken while the telescope follows Lissajous curves without switching the secondary. An automated pipeline merges the GISMO data with the telescope data streams to create FITS files which are automatically processed by the reduction software crush to create logs, pointing results, and a first quick view of the data.

The 2mm spectral range provides a unique terrestrial window enabling ground-based observations of the earliest active dusty galaxies in the universe and thereby allowing a better constraint on the star formation rate in these objects.

=== Observations ===

During the first open observing run in April 2012, observations will be carried out as pooled observations from a dedicated pool account gismow11. M.Gonzalez will provide login information. Progress of observations can be followed via the [[https://herapool.iram.es|pool data base]].

 * GismoHowToObserve (restricted access) <<BR>>
   This page presents pako scripts to be used for observations. They are currently being prepared by J.Abreu and H.Ungerechts.

=== Call for proposals ===

In September 2011, GISMO had for the 1st time been offered to the community. Two weeks of dedicated GISMO observations are now planned for April 2012. GISMO will be available again for the summer semester 2012.
