Abstract
The properties of a broadband sound detector utilising microwave-phonon-assisted tunnelling in superconductors are described. Using Al-Pb tunnel diodes at 1·3 °K, the sensitivity of the detector to 9·3 × 109c/s sound waves was found to be approximately 2 × 10−4V/W cm−2. At high frequencies the sensitivity is expected to increase as the square of the sound frequency.
