A method to measure transient heat transfer to liquid helium from a thin metal film heater under the condition of pulsed heating during r < 400 ns is proposed. The experimental equipment used for the measurements is described. The method is based on the comparison of heat pulses transfered from the

โฆ Synopsis
The temperature rise due to a step-wise pulse current/heat through horizontally immersed thin wires in a bath of sub-cooled superfluid helium (HelIp) is studied. Simplifications are made to establish the mathematical model according to the transient heat transfer characteristics of Hellp. The computer-simulated theoretical results are found to fit the experimental results well.
