We are building a bolometer camera (the Goddard-IRAM Superconducting Millimeter Observer, GISMO) for operation in the 2 mm atmospheric window to be used at the IRAM 30 m telescope. The instrument uses a 16 × 8 planar array of multiplexed TES bolometers that incorporates our newly designed Backshort Under Grid (BUG) architecture. Due to the size and sensitivity of the detector array (the NEP of the detectors is 3 × 10-17 W Hz-1/2), this instrument will be unique in that it will be capable of providing significantly greater imaging sensitivity and mapping speed at this wavelength than has previously been possible. The major scientific driver for this instrument is to provide the IRAM 30 m telescope with the capability to rapidly observe Galactic and extragalactic dust emission, in particular from high-z ULIRGs and quasars, even in the summer season. The 2 mm spectral range provides a unique window to observe the earliest active dusty galaxies in the universe and is well suited to better constrain the star formation rates in these objects. The instrument will fill in the SEDs of high-redshift galaxies on the Rayleigh-Jeans part of the dust emission spectrum, even at the highest redshifts. The observational efficiency of a 2 mm camera with respect to bolometer cameras operating at shorter wavelength increases for objects at redshifts beyond z ˜ 1 and is most efficient at the highest redshifts, at the time when the first stars were re-ionizing the universe.
