AN EXPERIMENT WHICH MEASURES RESONANT MODE CONVERSION IN He II
Overview & Synopsis
The results of an experiment to observe the non-linear conversion of second sound to first sound within a waveguide are described. The non-linear term which dominates the coupling between the two modes arises from the Galilean invariant ([MATH])2. Measurements show that the resonant mode conversion occurs precisely at the predicted frequency. Unique procedures were used to get absolute calibration of the first sound transducers and using these calibrations we find the amplitude of the mode converted first sound has its theoretically predicted value.
