A variable temperature dielectric cell for solids and liquids from DC to 200 megacycles

摘要

The cell, shown in Fig. 1, consists primarily of two quartz tubes, upon which are fastened metal electrodes. One quartz tube is mounted on a movable carriage rolling on invar rods which serve as ways. The other tube is rigidly mounted on the bed. A large metal cylinder encloses the electrodes, forming a resonant cavity, which may be modified for use at lower frequencies by switching in one of a series of coils. At audio frequencies connection can be made to a bridge.
