Condition of Multibubble Sonofusion and Proposal of Experimental Setup

Abstract

We consider that multibubble sonoluminescence (MBSL) sonofusion is necessary for the industrial use of sonofusion. In 2002, Taleyarkhan et al. [Science, 295, 1868, (2002)] reported neutron radiation from single-bubble sonoluminescence (SBSL), thereafter sonofusion has been discussed. However, SBSL, as described in the literature, is only one bubble, then the energy of sonofusion has a strict limitation for industrial use, that is, very little production of energy. MBSL is a cluster of bubbles; therefore, if sonofusion occurs in MBSL, a large amount of energy can be obtained. We assume the difference between SBSL and MBSL is temperature, thus we propose experimental setup of sonofusion, in which sonoplasma raises the temperature of MBSL.
