Detecting sound wave of bubbles produced in a boiling liquid

This experiment attempted to detect the sound wave produced by bubbles in boiling water and liquid nitrogen as an application for LUX, large underground xenon, which is expected to detect weakly interacting massive particles, WIMPs. Currently, there are still several steps needed to be done in order to detect the bubble waveform. Before proceeding any further, it is necessary to change the current setup by using a device that will boil water without producing noise and that will release one bubble at a time. In this way, it will be easier to identify a bubble’s waveform on the oscilloscope. Also, a microphone more sensitive than the piezo crystals may be needed to detect bubbles produced from a boiling liquid. Otherwise, a smaller vessel may help increase the piezo microphones’ sensitivity to the changes within the vessel. Once an appropriate microphone has been found that will detect bubbles from boiling water, liquid nitrogen should be used to better emulate the conditions found in LUX.
