- In this paper we describe the construction and performance of a primary ultra-low temperature thermometer, the current sensing noise thermometer. The thermometer uses a SQUID to measure the Thermal Johnson noise in a resistive element. The work was carried out in collaboration with international standards laboratories and has been used to support the new 2019 redefinition of the Kelvin as part of the Mise en pratique (How in practice to use the new scale, https://www.bipm.org/utils/en/pdf/si-mep/MeP-K-2019-LT_Johnson_Noise_Thermometry.pdf)
