Abstract
In January 2000 an EU collaborative project was established to research into methods of disseminating the temperature scale below 1 K. The scale which was formally adopted by the Comite International des Poids et Mesures in October 2000, is the Provisional Low Temperature Scale of 2000 (PLTS-2000). It covers the range of temperature from 1 K down to 0.9 mK, and it is defined by an equation for the melting pressure of He-3.
The project will develop and evaluate thermometers, fixed points and instrumentation needed to disseminate the scale to users. Several thermometers are being developed, including Coulomb blockade, noise and magnetic thermometers. A superconducting reference device with 10-12 samples is being fabricated to act as a fixed-point device. The full scale, including the He-3 transition temperatures, will be realised in several laboratories, and the thermometers and devices will be examined for research, metrological and industrial use.
