ILL3 is a cryofurnace which allows in principle temperatures from 2 K to 600 K without touching the sample. However, there are some drawbacks:

  • for high temperatures, one needs a special power supply for boosting the heating power.
  • for temperatures > 300 K the consumption of LHe (liquid helium) increases drastically
  • it is possible to work without LHe, under the condition, that the main vacuum is pumped constantly. The use of LN2 (liquid nitrogen) is mandatory.
  • the consuption of liquids may be reduced by removing the exchange gas. But this will affect the temperature of the sample, the difference to the sensor temperature might get untolerably high.
