A HISTORY OF CRYOGENICS.

Author(s) : JOHNSON V. J.

Summary

THE TERM < CRYOGENICS > IS USED TO DESIGNATE THE LOWEST TEMPERATURE RANGE, ROUGHLY FROM 123 K (-150 DEG C) DOWN TO ABSOLUTE ZERO. THE AUTHOR RELATES THE EFFORTS OF THE PIONEERS TO LIQUEFY THEATMOSPHERIC GASES AND THE DEVELOPMENT OF TECHNIQUES TO ACHIEVE VERY LOW TEMPERATURES. THESE DEVELOPMENTS HAVE LED TO WIDE INDUSTRIAL APPLICATIONS BUT HAVE REVEALED MANY UNUSUAL PHENOMENA IN NATURE. SOME OF THESE ARE THE WIDE-SCALE LIQUEFACTION OF GASES FOR STORAGE, TRANSPORT, AND REFRIGERATING PURPOSES ; SUPERCONDUCTIVITY, SUPERFLUIDITY OF LIQUID HELIUM, THE DILUTION REFRIGERATOR FOR ACHIEVING MILLIDEGREE KELVIN TEMPERATURES, THE < HYDROGEN > BOMB, CRYOSURGERY AND BIOLOGICAL MATERIAL PRESERVATION.
