We studied a Single Bubble Sonoluminescence system consisting of an Argon bubble in a Sulfuric Acid aq. solution. We experimentally determined the relevant variables of the system. We also measured the bubble position, extent of the bubble orbits and light intensity as a function of acoustic pressure for different Argon concentrations. We find that the Bjerknes force is responsible for the bubble mean position and this imposes a limitation in the maximum acoustic pressure that can be applied to the bubble. The Rayleigh-Taylor instability does not play a role in this system and that at a given gas concentration, the SL intensity depends more on the bubble time of collapse than any other investigated parameter.
