Talks of the 221st PTB seminar "Workshop on progress in determining the Boltzmann constant", held on 19th October 2006 in Berlin
2007
PTB-Th-3
17
New dielectric-constant gas thermometry (DCGT) measurements were performed at PTB in the temperature range from 2.4 K to 26 K in order to establish a temperature scale with reduced uncertainty. The progress concerning the measurement of capacitance changes, temperature and pressure compared with the results published in 1996 are described in detail. The work done is the first step on the way to determine the Boltzmann constant at the triple point of water.

PTB-96, the ultra-low temperature scale of PTB
2005
PTB-Th-2
37 S.
The establishment of the ultra-low temperature scale at PTB in the range from 1 mK to 1 K, and its transfer to the .sup.3.nosup.He melting pressure equation, is described. The temperature scale, which has been constructed with magnetic thermometry to obtain a smooth pressure-temperature relation over a wide range, ultimately relies on primary noise thermometry. The construction and verification of the scale is discussed, and a comparison with other temperature scales is presented.

Platinum NMR thermometry below 0.1 K
2004
PTB-Th-1
36 S.
The construction of the temperature scale PTB-96 below 15 mK relies mainly on the Curie law of platinum NMR. Therefore the validity of the Curie law is critically reviewed with respect to the properties of platinum including the effect of magnetic impurities and radiation damping. Equipment and procedures are described that were employed to limit potential degradations of the Curie law. Measurements with other thermometers supporting the NMR results are presented. An uncertainty budget concerning the actual material, instrumentation, and signal processing is given.
