Cryogen Free Superconducting Magnet (FIST)

Cryogen-free superconducting magnets have become increasingly popular in research and industry due to their ease and simplicity of operation as compared to traditional liquid helium cooled magnet systems. These magnets are manufactured in a variety of configurations and sizes to accommodate requirements of most imaginative scientists or engineers. Cryogen free magnet systems use a closed cycle helium refrigerator to cool the cryogenic assemblies to temperatures close to 4K. In certain configurations the magnet is conductively cooled in a vacuum whereas some geometries use traditional LHe cooling with a cryocooler to recondense liquid Helium; thereby resulting in near zero loss system (ReCon TM ). Based on customer’s experimental requirements either a Gifford-McMahon or a pulse tube cryocooler is used.
Faculty across different departments in the Institute have taken advantage of this equipment for getting data for sponsored research. PhD scholars and M tech students of Cryo. Engg. Centre and a number of students from other departments like Physics, Material Science, Metallurgy are being benefited from this facility. Resistive and magnetoresistive data for projects related to soft magnetic materials, Heusler alloys, Magneto resistive material and spintronics were taken in using this facility. Isothermal magnetic field sweeps and temperature sweeps at different field sweeps were taken on magneto caloric samples for refrigeration applications. A list of research projects under taken and papers related to this is given in a separate sheet. The academic courses offered in the centre are M. Tech. in Cryogenic Engineering M.S. in Cryogenic Engineering and Ph. D. The research in the centre is highly interdisciplinary in nature a number of faculties are also offering continuing education programme in different fields. Research project related to Cryogenic materials, nanofluids, Cryogenic refrigeration, Superconducting magnets and devices, Natural gas processing, Gas hydrates, Compact heat exchangers, Hydrogen Energy and Air separation technology. In Cryogenic Engineering Centre, MTech students comprising various background like physics, electrical, mechanical, chemical and other engineering disciplines go through an experiment on high field low-temperature FIST facility as a part of their curriculum.
