CM10336 - The first experimental evidence that demonstrates a high-temperature plasma
formation (higher than 1 million K) in liquid metal with ultrasonic waves is
given. The key aspect of this experiment deals with a cavitating target in
the liquid Li formed by ultrasonic waves, and the target is bombarded with
deuteron beams (Ed ~ 50 keV) to explore nuclear environments where fusion
reactions can be enhanced very strongly. The striking result is that the
yield of the 2H(d,p)3H reaction increases substantially when cavitation is
turned on and the proton peak becomes broader with a small tail on the
high-energy side. Kinematical analyses indicate a temperature around 600 eV
(~7 million K) of deuterons in the interior of the bubble. The experimental
results obviously show strong reaction enhancement, although no bubble
fusion (or sonofusion) events are observed.
