Division of Low Temperature and Superconductivity (DLTS) is the successor of the Department of Low Temperatures, from which the Institute of Low Temperature and Structural Research originated, when it was brought into existence on 1 October 1966. Since the beginning, fundamental interests of the Division have been superconductivity, thermal properties of solids and the development and use of cryogenic techniques. The current list of subjects does not differ much from that, focusing on high-temperature superconductivity research, transport of heat in solids and cryocrystals. The place of cryotechnology has been taken over by cryothermometry, which resulted in founding the Laboratory of Temperature Standard at DLTS, which is a depositary of the national temperature standard in the Institute.
