The Goddard-IRAM Superconducting 2mm Observer (GISMO) is a bolometer camera for the IRAM 30m telescope. 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 125-175GHz, pixels are spaced by 14", the telescope HPBW is 16.7". In the standard observing mode, data are taken while the telescope follows Lissajous curves without switching the secondary. An automated pipeline merged the GISMO data with the telescope data streams to create FITS files for further processing by the reduction software crush.

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.
