USE OF LOW TEMPERATURE
October 26, 1959
A. J. Curtis of the National Bureau of Standards is using a special holder designed for use from the liquid-nitrogen range up to 300 degrees C.
To achieve the very low temperatures, the holder (center) is placed in a Dewar containing liquid nitrogen.
The top of the Dewar, which can be conveniently raised up to the holder, can be seen at table level.
At left is a modified commercial resonant circuit and directly in front of the scientist a capacitance bridge.
