Sentences with word «bolometer»

Submillimetre Common - User Bolometer Array, James Clerk Maxwell Telescope, JAC (Cold dust disk around Vega)

In 1896, noting that moonlight had to pass through more atmosphere when the Moon was lower in the sky (a nice paradox to entertain grade schoolers with), Swedish Nobelist Svante Arrhenius used the recently invented Langley bolometer to plot IR from the Moon as a function of its altitude.

MUSTANG - 2 is the successor to the GBT's pathfinder 3 mm bolometer camera, MUSTANG, and represents a large step forward in sensitivity, fidelity, and robustness.

Rainer Weiss in his lab in MIT's Building 20 in the late 1970s, working on radiation detectors called bolometers.

The BICEP2 detectors are polarization sensitive bolometers made from a pair of transition edge sensors coupled to orthogonal phased antenna arrays.

In addition, the complexity of these instruments required a diversity of technologies (e.g., adaptive optics, multifiber spectrographs, submillimeter bolometers) not necessarily available in a single country.

In addition to transitioning to a separate organization, we have two new high frequency instruments coming online this winter — MUSTANG2, a 70 - 105 GHz, 210 element bolometer array, and ARGUS, a 75 - 116 GHz, 16 element focal plane array.

Two new 3 - mm wavelength instruments are having an excellent first full high frequency season — ARGUS, a 16 - pixel spectroscopy contend, and MUSTANG - 2, a 223 - pixel feedhorn bolometer — and we are looking forward to publication of the instrument's science results....

The performance of the newly completed MUSTANG - 2 bolometer camera has been verified on the 100 - meter Green Bank Telescope and astronomical observations have begun.

On July 6, 2004, a team of astronomers (including Jane Greaves, Mark Wyatt, Wayne Holland, and William Dent) using the Submillimetre Common - User Bolometer Array (SCUBA) of the James Clerk Maxwell Telescope at the Joint Astronomy Center on the Big Island of Hawaii announced that they had detected a large and relatively dense, cold dust disk around Tau Ceti (RAS press release; and (Greaves et al, 2004).

While mechanical detection of IR radiation has been possible since Samuel Pierpont Langley invented the bolometer in 1880, devices that also can recognize and identify an IR source after detection have been more challenging to develop.

The bolometer has also been used to measure the temperature of the moon's surface through a telescope.

Instruments for detecting infrared radiation include heat - sensitive devices such as thermocouple detectors, bolometers (some of these are cooled to temperatures close to absolute zero so that the thermal radiation of the detector system itself is greatly reduced), photovoltaic cells, and photoconductors.

The bolometer is essentially a very sensitive thermometer.

Bolometer, an instrument used to measure infrared, or heat, radiation.

I am reminded of some work I did a long time ago, when we were simulating the behaviour of a bolometer maintained at a constant temperature with a feedback loop.

By 1880, Langley's bolometer was refined enough to detect thermal radiation from a cow a quarter of a mile away.

In particular, Langley's electric instrument, the bolometer, vastly increased the sensitivity with which radiation could be observed.
