  Title Sensitive Hot Wire Level Detector for Cryogenic Liquids Type Journal Article
  Year 1969 Publication Review of Scientific Instruments Abbreviated Journal Rev. Sci. Instrum.  
  Volume 40 Issue 3 Pages 483-486  
  Keywords  
  Abstract A very simple and highly sensitive ``hot wire'' type level detector to be used with cryogenic liquids is described. The hot filament is made of tungsten wire of about 4 µ diam. The tests on the sensor were made moving the filament in and out of the quiescent surfaces of liquid helium and nitrogen. The results showed 0.006 mm sensitivity in the determination of liquid helium level and 0.002 mm sensitivity in the case of liquid nitrogen level. The sensor is assembled in such a way that it can be used without special precautions during indefinite periods of time. For the case when the full capabilities of the sensor are not necessary, a simple circuit is presented.

  Title Experimental Heat Capacity of Pure Liquid He3 Type Journal Article
  Year 1969 Publication Physical Review Abbreviated Journal Phys. Rev.  
  Volume 177 Issue 1 Pages 266-271  
  Keywords  
  Abstract Measurements of the heat capacity of pure He3 at 0.24 atm obtained by a differencing method are presented for the temperature range from 20-150 m°K. The temperature scale T* used is that valid for powdered cerium magnesium nitrate in the form of a right circular cylinder with diameter equal to height. There is excellent agreement between the present and earlier measurements. Considering all low-pressure difference data we find that from 6-125 m°K the ratio of heat capacity to magnetic temperature decreases linearly with increasing temperature. The relationship of the measurements to the temperature scale and to theories of spin fluctuations in He3 is also discussed.
