Project: Implementing the new Kelvin
The SI unit of temperature – the kelvin – is to be redefined in terms of the Boltzmann constant, which relates energy at the individual particle level with temperature. This redefinition, along with other recent advances in temperature metrology, will enable a fundamental change in the way we measure temperature. Current temperature scales rely upon a set of fixed points determined by primary thermometry. This project will improve primary thermometry at temperatures ranging from 0.0009 K to over 3000 K and will assign definitive thermodynamic temperatures to a set of high temperature fixed points for the first time. This, along with new sensing methods and techniques, will allow extreme temperature measurements to be linked to a direct realisation of the kelvin. The results will benefit the large number of industries that measure temperature on a daily basis, in particular low temperature industries such as cryogenics and high temperature industries such as steel production.
