Abstract
A high-temperature (up to 1600°C) installation for measuring the coefficient of linear expansion (CLE) using a relative method is described. The measuring unit is installed in a protective glove box, which allowed measurements to be performed on samples irradiated in a reactor. Changes in the length of the sample during heating were recorded with a clock-type indicator head with an accuracy of 1 μm with the measurement range of 0–10 mm. The installation was used to determine the values of swelling of irradiated samples during high-temperature annealing and to obtain the values of the CLE of promising reactor materials. The average relative measurement error is 8–11%.
期刊介绍：
Instruments and Experimental Techniques is an international peer reviewed journal that publishes reviews describing advanced methods for physical measurements and techniques and original articles that present techniques for physical measurements, principles of operation, design, methods of application, and analysis of the operation of physical instruments used in all fields of experimental physics and when conducting measurements using physical methods and instruments in astronomy, natural sciences, chemistry, biology, medicine, and ecology.
