Laboratory of electromagnetic measurements
Contact info: Ing. Šouc Ján, CSc.
Measurement equipment designed for magnetization AC losses of superconductors in external magnetic field of magnitude up to 100 mT at variable temperatures from 15.5 K to room temperature with the precise temperature stabilization of 10-3K.
Laboratory of Composite Superconductors
Contact info: Ing. Hušek Imrich
Laboratory of composite superconductors is well equipped for the complete manufacturing of composite wirers / tapes and cables. Rotary swaging, drawing as well as traditional and special rolling techniques (active two-axial rolling, eccentric rolling) are used. Circular and flat cables consisting from 3-12 strand can be made in the unit lengths of hundred meters. Heat treatments of powders, metals and composite wires and windings can be done in oxygen atmosphere, vacuum or in the inner gas.
