Dilatometry at low temperatures

Abstract

A dilatometer has been constructed for the routine measurement of thermal expansion coefficients in the temperature range of 0.1–10 K. Using a SQUID detector, the dilatometer provides a resolution of 2×10−4 Å. As a test of this apparatus, the linear thermal expansion coefficient of high-purity copper has been measured between 0.2 and 9 K.
