STRAIN MEASUREMENTS AT CRYOGENIC TEMPERATURES AND HIGH MAGNETIC FIELDS.

Author(s) : FERRERO C.

Summary

THE DESIGN AND CONSTRUCTION OF LARGE-SIZE SUPERCONDUCTING MAGNETS FOR RESEARCH WORK ON FUSION GAVE RISE TO SEVERAL PROBLEMS CONCERNING THE PROPERTIES OF SUPERCONDUCTING COMPOSITE CABLESAND OF THE MATERIALS FOR MAGNET CONSTRUCTION. IN CONNECTION WITH MAGNET CONSTRUCTION, THE PARTICULAR SIGNIFICANCE OF THE MEASUREMENT OF STRAINS BROUGHT ABOUT BY THERMAL AND ELECTRODYNAMIC SOURCES IN SUPERCONDUCTING COILS AND SUPPORT STRUCTURES IS POINTED OUT ; STRAIN GAGES HAVE CONSEQUENTLY TO BE CHARACTERIZED VS TEMPERATURE AND MAGNETIC FIELDS. THE INVESTIGATION CARRIED OUT HAS ANALYSED THE BEHAVIOUR OF COMMERCIAL-TYPE NICKEL-CHROMIUM (KARMA) ALLOY STRAIN GAGES IN HIGH MAGNETIC FIELDS (6 T) AND AT A 4.2 K TEMPERATURE. THE PAPER SUPPLIES APPARENT-STRAIN CURVES AND EVALUATES THE VARIATION OF CALIBRATION FACTOR K VS MAGNETIC FIELD.
