Nuclear emissions during self-nucleated acoustic cavitation.

Area of Science:

• Nuclear Physics
• Fusion Energy Research
• Acoustic Inertial Confinement

Background:

• Acoustic inertial confinement is an emerging technique for achieving nuclear fusion.
• Previous research has explored various methods for initiating fusion reactions, but novel approaches are continually sought.

Purpose of the Study:

• To test a new stand-alone acoustic inertial confinement nuclear fusion device.
• To investigate nuclear emissions from self-nucleated bubbles in different liquid types without external neutron sources.

Main Methods:

• Utilized a novel acoustic inertial confinement fusion device.
• Conducted experiments with four liquid types, focusing on self-nucleated bubble formation.
• Employed four independent detection systems: neutron track plastic detector, a detector, NE-113 liquid scintillation detector, and NaI gamma ray detector.

Main Results:

• Observed statistically significant nuclear emissions from deuterated benzene and acetone mixtures.
• Detected neutron energy <= 2.45 MeV, consistent with deuterium-deuterium (D-D) fusion.
• Measured neutron emission rates between approximately 5x10^3 n/s and 10^4 n/s, exhibiting inverse distance dependence.

Conclusions:

• The acoustic inertial confinement device successfully demonstrated statistically significant nuclear emissions indicative of D-D fusion.
• Deuterated benzene and acetone mixtures showed promise, while heavy water did not yield significant emissions.
• The results suggest the potential of acoustic inertial confinement as a viable method for fusion energy research.
