Bubble fusion

“Bubble fusion”, also known as “Sonofusion” provides us with a considerably simpler and cheaper means of thermonuclear fusion study. The application of deuterium ions in fusion helps to reduce the reaction cost as well as improve the reaction efficiency, since deuterium can withstand considerable stress and resultant stretching. The hazard factor also gets reduced compared to other nuclear fusion reactions.
Sonofusion phenomena occur when bubbles implode. This paper reviews the status of understanding the bubble dynamics involved in this phenomena. The experimental and analytical evidence supporting the observed production of neutrons and tritium due to thermonuclear fusion within imploding bubble clusters is reviewed. Also some potential methods to scale up the neutron yield as well as the applications of bubble fusion are discussed.
