Single-bubble sonoluminescence
Single-bubble sonoluminescence occurs when an acoustically trapped and periodically driven gas bubble collapses so strongly that the energy focusing at collapse leads to light emission. Detailed experiments have demonstrated the unique properties of this system: the spectrum of the emitted light tends to peak in the ultraviolet and depends strongly on the type of gas dissolved in the liquid; sm...
متن کاملDigital Oscillograph
Design Introduction The digital storage oscillograph uses a microprocessor for control and data proccesing. It performs a variety of functions that simulation oscillographs cannot, such as leading triggering, combined triggering, burr capture, wave processing, hard-copy export, soft-disk recording, and long-term waveform storage. Typically, the digital storage oscillograph’s bandwidth exceeds 1...
متن کاملEffects of ionization in single-bubble sonoluminescence.
We studied the effects of ionization in a sonoluminescing (SL) bubble within the hydrodynamic framework. The thermodynamic variables and the degrees of ionization inside the bubble throughout an oscillation cycle are obtained by solving the hydrodynamic equations assuming spherical symmetry. Several models are used to compute the emitted radiation, which are then compared with experimental data...
متن کاملDirect observations of single sonoluminescence pulses
Previous reports have described experimental measurements and theoretical descriptions of sonoluminescence without clearly resolving the physical events that underlie this phenomenon. Although incomplete, these results have led to suggestions that sonoluminescence might be such an extreme process that it could serve as an unusual inertial confinement source of fusion neutrons. Such a possibilit...
متن کاملHarmonic enhancement of single-bubble sonoluminescence.
It is known from experiment that the light emission from a sonoluminescing bubble can be increased by using more than one driving frequency. In this paper, a systematic method to determine the optimal conditions of pressure amplitude and relative phase for this effect is described. As a specific application, a two-frequency system--26.5 kHz and 53 kHz--is considered. It is found that the maximu...
