“…The trend in bolometer development is such that sensitivity, defined as the noise equivalent power (NEP), is increased by lowering the operating temperature of the bolometer. This is true for both types of the most commonly developed bolometers: the transition edge sensor (TES) [3][4][5] and the kinetic inductance detector (KID) 6 .…”

Bolometers for balloon and space missions have seen extensive development because of their capacity to test primordial conditions of the Universe. The major improvements consist in lowering the operating temperature to reach higher sensitivities. Here we show that an array of 192 cold-electron bolometers (CEB) demonstrates photon-noise-limited operation at the cryostat temperature of 310 mK due to effective self-cooling of the absorber. The direct electron cooling of nanoabsorber placed between normal metal-insulator-superconductor junctions has considerably higher efficiency than indirect cooling through massive suspended platform, that requires overcoming a weak electron-phonon conductance. The electron temperature reached 120 mK without a power load, and 225 mK with a 60 pW power load with self-noise of a single bolometer below 3 Á 10 À18 W Hz À1=2 at a 0.01 pW power load. This bolometer works at electron temperature less than phonon temperature, thus being a good candidate for future space missions without the use of dilution refrigerators.

The OSS on the Origins Space Telescope is designed to decode the cosmic history of nucleosynthesis, star formation, and supermassive black hole growth with wide-area spatial-spectral 3-D surveys across the full 25 to 590 micron band. Six wideband grating modules combine to cover the full band at R=300, each couples a long slit with 60-190 beams on the sky. OSS will have a total of 120,000 background-limited detector pixels in the six 2-D arrays which provide spatial and spectral coverage. The suite of grating modules can be used for pointed observations of targets of interest, and are particularly powerful for 3-D spectral spectral surveys. To chart the transition from interstellar material, particularly water, to planetary systems, two high-spectral-resolution modes are included. The first incorporates a Fourier-transform spectrometer (FTS) in front of the gratings providing resolving power of 25,000 (δv = 12 km/s) at 179 µm to resolve water emission in protoplanetary disk spectra. The second boosts the FTS capability with an additional etalon (Fabry-Perot interferometer) to provide 2 km/s resolution in this line to enable detailed structural studies of disks in the various water and HD lines. Optical, thermal, and mechanical designs are presented, and the system approach to the detector readout enabling the large formats is described.

“…This sets the QCD apart from the other approaches, which have to date not demonstrated NEPs lower than 0.95 × 10 −19 W∕Hz 1∕2 in a single pixel demonstration or 2 × 10 −19 W∕Hz 1∕2 in a kilopixel demonstration. [12][13][14] Another important attribute of the QCDs is its speed-the devices are intrinsically fast, and the combination of sensitivity and speed enables photon counting. In an experiment using a fast readout, the QCD has demonstrated 1.5 THz (200 μm) photon counting under a range of loadings.…”
