1. Ultra-Sensitive Chip-Based Photonic Temperature Sensor Using Ring Resonator Structures
Haitan Xu, Mohammad Hafezi, Jingyun Fan, Jacob M Taylor, Gregory F Strouse, Zeeshan Ahmed
Temperature is one of the most measured quantity in the world, second only to time. Recently there
has been considerable interest in developing photonic temperature sensors to leverage advancements in
frequency metrology. Here we show that Silico ...
2. Picometer metrology for precise measurement of refractive index, pressure, and temperature
Jack A Stone Jr, Patrick F Egan, Jay H Hendricks, Gregory F Strouse, Douglas A Olson, Jacob E Ricker, Gregory E Scace
For several years we have been studying the use of Fabry-Perot interferometers for precise measurement of the refractive index of gasses, where the primary motivation has been to improve interferometer-based length measurement. Because the refractiv ...
3. Room Temperature Acoustic Transducers for High-Temperature Thermometry
Dean C Ripple, William E. Murdock, Gregory F Strouse, Keith A Gillis, Michael R Moldover
We have successfully conducted highly-accurate, primary acoustic thermometry at 600 K using a sound
source and a sound detector at room temperature. We describe the source, the detector, and the ducts that connected them to our cavity resonator. Thi ...
4. Thermal Analysis of Refrigeration Systems Used for Vaccine Storage
NIST Interagency/Internal Report (NISTIR)
Michal J Chojnacky, W Wyatt Miller, Dean C Ripple, Gregory F Strouse
Each year, billions of dollars of vaccines are stored in refrigerators at the facilities of a variety of medical providers. Many vaccines must be maintained in the range 2 °C to 8 °C to retain product potency. We have tested the performance of two t ...
5. NIST-NRC COMPARISON OF TOTAL IMMERSION LIQUID-IN-GLASS THERMOMETERS
Kendra Hill, D.J. Gee, Christina Dawn Cross, Gregory F Strouse
The use of liquid-in-glass thermometers is described in many documentary standards in the fields of environmental testing, material testing, and material transfer. Many national metrology institutes, including the National Institute of Standards and ...
6. Observations on Non-Uniqueness and Uncertainty in the SPRT Interpolations of ITS-90
Douglas R White, Gregory F Strouse
7. Maintenance and Validation of Liquid-in-Glass Thermometers
Special Publication (NIST SP)
Christina Dawn Cross, Dean C Ripple, Gregory F Strouse
Liquid-in-glass thermometers are pervasive in use throughout industry and provide a convenient method for measuring temperature over for a broad range of applications with reasonable stability and accuracy. However, liquid-in-glass thermometers are ...
8. Recommended List of Common Impurities for Metallic Fixed-point Materials
of the ITS-90
Dean C Ripple, Anatoly Pokhodun, Peter Steur, Gregory F Strouse
Working Group 1 of the Consultative Committee for Thermometry (CCT) has recommended methods for estimating the uncertainties of fixed-point temperatures attributable to chemical impurities . These methods require chemical analysis of all commonly ...
9. Standard Platinum Resistance Thermometer Calibrations from the Ar TP to the Ag FP
Special Publication (NIST SP)
Gregory F Strouse
The National Institute of Standards and Technology (NIST) is in charge of realizing, maintaining,
and disseminating the international Scale of 1990 (ITS-90). The Standard Platinum Resistance
Thermometer (SPRT) Calibration Laboratory of the NIST ...
10. Acoustic Thermometry Results From 271 K to 552 K
Dean C Ripple, Gregory F Strouse, Michael R Moldover
The NIST Acoustic Thermometer determines the thermodynamic temperature from measurements of ratios of the speed of sound of argon in a spherical cavity. We report recent results for T - T90 on 12 isotherms spanning the range 271 K to 552 K. (T is th ...
