Implementing the new kelvin 2

Project: EU project

Project Details


Primary thermometry for the redefinition of the kelvin.

Primary thermometry methods will be needed to support the redefinition of the kelvin in terms of the Boltzmann constant.

Project develops primary thermometry for the realisation of the new kelvin and an ultra-reliable data set of thermodynamic temperatures.

VTT MIKES develops primary thermometry based on Coulomb blockade for the ultra-low temperature region from 1 K down to 10 mK.
