Summary

THE AUTHORS PRESENT AN EXTENSIVE STUDY ON THE BEHAVIOUR OF TIME DEPENDENT HEAT TRANSFER IN SUBCOOLED HE II UNDER CONDITIONS WHICH ARE CLOSELY RELATED TO THE COOLING PROBLEM OF SUPERCONDUCTING MAGNETS. EXPERIMENTAL RESULTS ON THE DELAY FOR ONSET OF BURNOUT AND ON THE TRANSIENT RECOVERY FROM BURNOUT ARE DISCUSSED. A THEORETICAL MODEL IS DERIVED FROM THE ASSUMPTION THAT HEAT DIFFUSION CHARACTERIZED BY THE GORTER-MELLINK EQUATION IS THE DOMINANT MODE OF HEAT TRANSFER AND THAT THERMAL WAVES PLAY NO DIRECT ROLE IN THIS CONNECTION. THE COMPARISON OF EXPERIMENTAL AND CALCULATED RESULTS SHOWS A VERY SATISFACTORY AGREEMENT WHICH FULLY VALIDATES THE MODEL.
