Type of article: Article
Summary
A BATH TYPE CRYOSTAT HAS BEEN DESIGNED AND FABRICATED FOR THE MEASUREMENT OF THERMAL EXPANSION OF MATERIALS BETWEEN 350 AND 80 K. THE CRYOSTAT CAN ALSO BE USED CONVENIENTLY TO EXPLORE THE DIELECTRIC PROPERTIES OF MATERIALS. SINCE THE METHOD OF MEASUREMENT REQUIRES A RATIO TRANSFORMER IMPEDANCE BRIDGE HAVING TWO INDUCTIVE ARMS, AND TWO THREE-TERMINAL CAPACITORS, THE RATIO TRANSFORMER HAVING SIX DECADES FABRICATED BY THE AUTHORS HAS BEEN USED. THE ACCURACY OF COMPARISON IS 2 PPM.
