ABSTRACT:
The vacuum properties of a cryogenic NMR probe maintained at a desired operating temperature by a cold head heat exchanger are improved by a separate heat exchanger operating below the temperature of the cold head heat exchanger for maintaining cryo-pumping surfaces at a temperature below said selected operating temperature.
