The authors study the effect of saturation pressure on the nonsteady critical heat flux during the boiling of liquid helium in a large volume. The tests were conducted in the pressure range 6-200 kPa and the working section on which the study was performed was a strip of brass foil 0.05 mm thick, 4mm wide, and 65 mm long. The tests were conducted with the working section horizontal, the heated side facing up. The method of study is described. Analysis of the oscillograms obtained in the tests showed that thorough heating of the working section occurred fairly rapidly after connection of the heater, and wall temperature changed negligibly over time immediately before the onset of the boiling crisis.
