Keywords: Johnson noise thermometry (5884301319).jpg Photograph of circuit used in NIST's Johnson noise thermometry system The system relies on the 'noise' of jiggling electrons as a basis for measuring temperatures It is extremely precise in part because it is based on the predictable quantum effects of superconducting elements located between the dashed slits on the top and bottom of the chip 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/5884301319/ Johnson noise thermometry 2008-05-30 14 49 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 N06/5884301319 2016-09-07 02 53 20 United States Government Work Uncategorized 2016 November 7 |
