Summary
[edit]DescriptionMicrowave Detectors; Sensors (5884864954).jpg |
Micrograph of a prototype NIST detector that will be used to seek B-mode polarization, the signature of the rapid inflation of the universe after the Big Bang. Cosmic radiation will be received by the arrow-shaped antennas in the middle of the detector. The antennas separate the radiation into two different polarization directions at a frequency of 145 gigahertz. (All light has two polarization directions.) Finally, the radiation for each polarization will be converted to heat by transition-edge sensors (top and right sides of the image), which precisely measure the energy using a superconducting metal that changes resistance in response to heat. The resulting data will be mapped to identify the polarization patterns.

Metadata
This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.
