THE TRIPLE POINT OF XENON: A CANDIDATE FIXED-POINT REFERENCE TEMPERATURE

K.D. Hill, A.G. Steele

Abstract

The triple point of xenon has recently been shown to be a suitable fixed point for incorporation into the next revision of the International Temperature Scale as a means to reduce the non-uniqueness in the important 84 K to 273 K range. We summarize the results, which illustrate that the xenon triple point itself is highly reproducible, with a standard deviation of 48 µK for the eight melts of this study, and a total realization uncertainty of just 76 µK.
