USE OF LOW TEMPERATUREE&MP 9.005 Dielectric Research 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. 27695-1-2386 (Fig 4)
