| Keywords: Microwave 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 Credit NIST Disclaimer Any mention of commercial products within NIST web pages is for information only; it does not imply recommendation or endorsement by NIST Use of NIST Information These World Wide Web pages are provided as a public service by the National Institute of Standards and Technology NIST With the exception of material marked as copyrighted information presented on these pages is considered public information and may be distributed or copied Use of appropriate byline/photo/image credits is requested https //www flickr com/photos/usnistgov/5884864954/ Microwave Detectors; Sensors 2011-06-29 08 31 https //www flickr com/people/63059536 N06 National Institute of Standards and Technology PD-USGov National Institute of Standards and Technology https //flickr com/photos/63059536 N06/5884864954 2016-09-07 02 53 13 United States Government Work Uncategorized 2016 December 20 | ||||
