Low Temperature Dilatometric Complex

Over-measuring lengths (especially when the dimensions of different components of physical and biological objects have to agree with each other) is an important and complex experimental problem. Depending on the systems in which the measurements need to be made, as well as the conditions in which they are located, mechanical, optical or electronic measurement methods are used. Scientists of the B. Verkin ILTPE of NASU  created a low-temperature dilatometric complex, the use of which allows to register thermal expansion in the scale of interatomic distances in the temperature range from 1.2 K to 300 K. The accuracy and temperature range of this complex is currently not has analogues in the world.
