More evidence of high energy ions in DPF

Pavel Kubes et al (IEEE Transactions on Plasma Science, 37, 83, Jan. 2009) present more evidence of high energy ions in a plasma focus.

Using the PF-1000 device in Warsaw, operating at 2 MA, Kubes et al measured the spread in neutrons energies in the down-axis, up-axis and cross-axis directions.

In all three directions there was large spread in neutrons energy around the 2.45 Mev generated by the nuclear reaction itself.

The peak of the energy distribution was at least around 300 keV (the equivalent of 3.3 billion C), somewhat higher than the energies we observed at a current of 1.4 MA in Texas.

The article cited above is a published version of the paper he and his colleagues presented last August at the International Z-pinch Conference.
