Summary

A CONTINUOUS FLOW CRYOSTAT IS BETTER SUITED WHERE TEMPERATURE ADJUSTMENT OVER A WIDE RANGE IS NECESSARY. IT WAS THEREFORE DESIGNED FOR THE STUDY OF DIELECTRIC AND THERMAL EXPANSION BEHAVIOUR BETWEEN 80 AND 300 K OF SOLID SAMPLES WHICH HAS TO BE DONE AT ABOUT 0.0013 PASCAL. TEMPERATURES UP TO 150 K COULD BE REACHED BY INCREASING THE OPENING OF A CONTROL VALVE NEAR THE SUCTION PUMP. FURTHER OPENING FOR OBTAINING LOWER TEMPERATURES REVEALED A SLOW OSCILLATION BETWEEN 150 AND 125 K. A POSSIBLE REASON IS GIVEN.
