Summary

THE PLASTIC DEWAR IS SUITED TO THE USE OF THE LARGE PULSE MAGNET AND SQUID BY MEANS OF ITS PROPERTIES AS THE ELECTRICAL INSULATOR AND NON-MAGNETISM. THREE PROBLEMS SHOULD BE SOLVED: 1) PERMEABILITY OF HELIUM GAS THROUGH THE PLASTIC WALL, 2) CRACKING BY MEANS OF THERMAL STRESS BETWEEN ROOM AND LIQUID HELIUM TEMPERATURE, AND 3) MECHANICAL PROPERTIES OF GLUING AT LIQUID HELIUM TEMPERATURE. THESE PROBLEMS ARE DISCUSSED. IT IS FOUND THAT THE PLASTIC MATERIALS MADE BY THE METHODS OF < FILAMENT WINDING > OR < VACUUM INJECTION > FOR THE LIQUID HELIUM DEWAR ARE EFFECTIVE.
