Realisation of the redefined kelvin

Project: EU project

Project Details


Bringing the new kelvin into a reality by primary thermometry while extending the life of the current scales.

In the redefined SI, the kelvin is defined in terms of a fixed value of the Boltzmann constant. Thus, practical methods to realise the kelvin in different temperature ranges need to be developed.

Project aims to turn the redefinition of the kelvin into a reality by developing primary thermometry.

VTT MIKES develops new Coulomb blockade thermometers (CBTs) optimized for the temperature range 1–25 K and demonstrates the dissemination of the kelvin by CBT in cooperation with an industrial partner.
