USE OF LOW TEMPERATURE

E&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.
