Titel: "Evidence of nuclear fusion neutrons in an extremely small plasma focus device operating at 0.1 Joules"

ABSTRACT

We report on D-D fusion neutron emission in a plasma device with an energy input of only 0.1 J, within a range where fusion events have been considered very improbable.
...
The neutron events observed are 20σ greater than the background.
...
A thorough understanding of this could possibly tell us where the theoretical limits actually lie, beyond conjectures. Notwithstanding, a window is thus open for low cost endeavours for basic fusion research. In addition, the development of small, portable, safe nonradioactive neutron sources becomes a feasible issue.

und aus der Conclusion

We conclude that there is enough scientific evidence that the NF, an extremely small plasma device operating at only 0.1–0.2 J, can produce D-D fusion reactions. Two independent sets of measurements in different laboratories (at our P4-Lab, CCHEN, in Chile, and at CAB, in Argentina) have confirmed the NF's neutron emission as a solid conclusion, with a close correlation between neutron detection and shots, excluding the existence of spurious signals on 3He systems. These results, and those obtained for a 50 J PF, permit us to anticipate that a device working at a few joules, with 103 to 104 shots at a frequency of 10 to 100 Hz, will produce a neutron yield of 104 to 106 events per second, although a more accurate determination of the absolute neutron yield could be desirable for this extrapolation. A deuterium-tritium mixture would boost this by up to 100 times.
...
Scientific questions raised by the results presented here are pertinent.
