我们已经开发了关键技术，使高度通用的，千像素辐射热计阵列的红外到毫米波长。我们最新的阵列架构基于我们的Backshort Under Grid（BUG）设计，该设计专门针对通过毫米相机和光谱仪为未来的地基，亚轨道和天基X射线和远红外线生产千像素大小的阵列。2007年11月，我们在西班牙的IRAM 30 m望远镜上展示了一个单片8x16 BUG测辐射热计阵列，该阵列具有2 mm间距探测器，用于使用我们的2 mm波长相机GISMO（戈达德IRAM超导2毫米观测器）进行天文观测。2毫米的光谱范围提供了一个独特的地面窗口，能够对宇宙中最早的活跃尘埃星系进行地面观测，从而能够更好地限制这些物体中的星星形成率。我们目前的初步结果，从我们的观察运行与第一场BUG测辐射热计阵列，并讨论仪器的性能。
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.
