Notes:
The stability of 19 germanium resistance thermometers manufactured in Kiev, USSR, has been studied by cycling them 30 times between temperatures of 20 and 300 K. Resistance measurements were made on each thermometer at 20 K on each cycle and also at 15 K on each cycle of the first 20 cycles. All but one of nine four-lead, standard-size thermometers were stable within the ±0.2 mK precision of the measurements at 20 K, while the observed changes in resistance at 20 K of 10 miniature thermometers correspond to temperature variations that ranged between 20 and 49 mK.
