Abstract
We have developed key technologies to enable highly versatile, kilopixel bolometer arrays for infrared through millimeter wavelengths. Our latest array architecture is based on our Backshort Under Grid (BUG) design, which is specifically targeted at producing kilopixel-size arrays for future ground-based, suborbital and space-based X-ray and far-infrared through millimeter cameras and spectroometers. In November of 2007, we demonstrated a monolithic 8x16 BUG bolometer array with 2 mm-pitch detectors for astronomical observations using our 2 mm wavelength camera GISMO (the Goddard IRAM Superconducting 2 Millimeter Observer) at the IRAM 30 m telescope in Spain. The 2 mm 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. We present preliminary results from our observing run with the first fielded BUG bolometer array and discuss the performance of the instrument.
