“…Each 64×40 detector array is itself comprised of two butted 32×40 backshort-under-grid (BUG) detector arrays developed at the Goddard Space Flight Center. [59], [60] The BUG detectors are constructed using transition-edge sensors hybridized with superconducting quantum interference device (SQUID) multiplexers, and have a pixel spacing of 1.135 mm.…”

Capabilities, performance, and status of the SOFIA science instrument suite

The Stratospheric Observatory for Infrared Astronomy (SOFIA) is an airborne observatory, carrying a 2.5 m telescope onboard a heavily modified Boeing 747SP aircraft. SOFIA is optimized for operation at infrared wavelengths, much of which is obscured for ground-based observatories by atmospheric water vapor. The SOFIA science instrument complement consists of seven instruments: FORCAST (Faint Object InfraRed CAmera for the SOFIA Telescope), GREAT (German Receiver for Astronomy at Terahertz Frequencies), HIPO (High-speed Imaging Photometer for Occultations), FLITECAM (First Light Infrared Test Experiment CAMera), FIFI-LS (Far-Infrared Field-Imaging Line Spectrometer), EXES (Echelon-Cross-Echelle Spectrograph), and HAWC (High-resolution Airborne Wideband Camera). FORCAST is a 5-40 µm imager with grism spectroscopy, developed at Cornell University. GREAT is a heterodyne spectrometer providing high-resolution spectroscopy in several bands from 60-240 µm, developed at the Max Planck Institute for Radio Astronomy. HIPO is a 0.3-1.1 µm imager, developed at Lowell Observatory. FLITECAM is a 1-5 µm wide-field imager with grism spectroscopy, developed at UCLA. FIFI-LS is a 42-210 µm integral field imaging grating spectrometer, developed at the University of Stuttgart. EXES is a 5-28 µm high-resolution spectrograph, developed at UC Davis and NASA ARC. HAWC is a 50-240 µm imager, developed at the University of Chicago, and undergoing an upgrade at JPL to add polarimetry capability and substantially larger GSFC detectors. We describe the capabilities, performance, and status of each instrument, highlighting science results obtained using FORCAST, GREAT, and HIPO during SOFIA Early Science observations conducted in 2011.

“…This, coincidentally, is the thickness of the silicon-on-insulator support wafer upon which the detectors are fabricated, making it a simple matter to mount the detector chip on a reflective surface, in our case a copper-coated alumina board, to serve as the back-short. We use a normal metal "Zebra" stripe structure on the TES devices, which is used to suppress excess noise [10] and indeed provides near fundamental-noise-limited performance of the devices [11].…”

Instrument performance of GISMO, a 2 millimeter TES bolometer camera used at the IRAM 30 m Telescope

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 spectrometers.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.

“…[1]). Our team has a long legacy in building and using TES based instrumentation, having successfully fielded FIBRE, the first TES based instrument with multiplexed readout [2], and recently the Goddard-IRAM Superconducting 2 mm Observer GISMO [3], which is available for astronomical observations (e.g. [4,5]) at the IRAM 30 m telescope in Spain through the regular IRAM call for proposals.…”

Design and Expected Performance of GISMO-2, a Two Color Millimeter Camera for the IRAM 30 m Telescope

et al. 2014

We present the main design features for the GISMO-2 bolometer camera, which we build for background-limited operation at the IRAM 30 m telescope on Pico Veleta, Spain. GISMO-2 will operate simultaneously in the 1 and 2 mm atmospherical windows. The 1 mm channel uses a 32 × 40 TES-based backshort under grid (BUG) bolometer array, the 2 mm channel operates with a 16 × 16 BUG array. The camera utilizes almost the entire full field of view provided by the telescope. The optical design of GISMO-2 was strongly influenced by our experience with the GISMO 2 mm bolometer camera, which is successfully operating at the 30 m telescope. GISMO is accessible to the astronomical community through the regular IRAM call for proposals.
