112. Temperature Scales Using Radiation Thermometers Calibratied From Absolute Irradiance and Radiance Responsivity
Published: Date unknown
Authors: Howard W Yoon, David W Allen, Charles E Gibson, Robert D. Saunders, Bettye C Johnson, Steven W Brown, Keith R Lykke
Abstract: In the International Temperature Scale of 1990 (ITS-90), temperatures above the freezing temperature of silver are defined with radiation thermometers calibrated using spectral radiance ratios to one of the silver-, gold- or copper-freezing temperatu ...

113. The NIST Eutectic Project: Construction of Co-C, Pt-C, and Re-C Fixed-Point Cell and Their Comparison With the NMIJ
Published: Date unknown
Authors: Howard W Yoon, Charles E Gibson, V B Khromchenko
Abstract: The National Institute of Standards and Technology (NIST) has initiated a project on novel high-temperature fixed points by use of metal (carbide)-carbon eutectics to lower uncertainties in thermodynamic temperature measurement not only the high -tem ...

114. The Realization and the Dissemination of Thermodynamic Temperature Scales
Published: Date unknown
Author: Howard W Yoon
Abstract: Since the establishment of the International Temperature Scale of 1190 (ITS-90), much progress has been made in the development of radiometers and blackbody sources. Cryogenic electrical-substitution radiometry is widely used in detector and radiome ...

115. Thermodynamic Radiation Thermometry for the Next SI
Published: Date unknown
Authors: Howard W Yoon, Charles E Gibson, V B Khromchenko, George P Eppeldauer, Robert R. Bousquet, Steven W Brown, Keith R Lykke
Abstract: We describe the construction, the calibration and the use of the NIST Thermodynamic Radiation Thermometer (TRT) to measure the temperature of the gold-freezing temperature blackbody and a variable-temperature blackbody from 800 ?C to 2700 ?C. These ...

116. Thermodynamic-Temperature Determinations of the Ag and Au Freezing Temperatures Using a Detector-Based Radiation Thermometer
Published: Date unknown
Authors: Howard W Yoon, David W Allen, Charles E Gibson, Maritoni Abatayo Litorja, Robert D. Saunders, Steven W Brown, George P Eppeldauer, Keith R Lykke
Abstract: We describe the development of a radiation thermometer calibrated for spectral radiance responsivity using cryogenic, electrical-substitution radiometry to determine the thermodynamic temperatures of the Ag- and Au-freezing temperatures. The absolut ...
