Sonofusion technology revisited

Sonoluminescence and sonofusion phenomena may occur when vapor bubbles implode. This paper reviews the status of our understanding of the bubble dynamics involved in these interesting phenomena. In particular, the experimental and analytical evidence supporting the observed production of neutrons and tritium due to thermonuclear fusion within imploding bubble clusters is reviewed and discussed from the perspective of nuclear engineers. Moreover, prospects for scaling-up the neutron yield and some possible applications of this exciting new technology are discussed.
