temperature resistance. The operating current for heating to T= 20K was 8-10 mA and the rate of evaporation of helium was then less than 1 cm -3 min -~ per cm heater length. For short periods, heating up to nitrogen temperature and above can be achieved; for 30 mA T~75K, V/l~lOcm 2 min.l and for a c
The time response of several carbon resistance thermometers has been measured in the liquid helium temperature range. The results are compared to the theoretical analysis of Komatsu and are found to be in fair agreement. The data indicate that carbon resistors have an intrinsic time response of the
