    This is from a workshop put on by S Lee and S H Saw in November 2010. Very nice color slides with technical explanations.

    Rather helpful and, if I read it correctly, it shows how the plasma focus idea was developed from the earlier Z-pinch, something I was unclear on before.

    This caught my attention on page 55 (possibly because it was in orange type): “neutron yields are non-thermonuclear in origin”.

    What does that mean? It’s my understanding that the word “thermonuclear” simply means “having to do with nuclear fusion” and not necessarily anything to do with Maxwellian distribution. Does this mean the plasma focus device doesn’t produce fusion neutrons? Given past controversies such as ZETA, cold fusion, and sonofusion, I’m aware of the importance of determining whether detected neutrons are indeed from a known fusion reaction, and I would hope everyone currently involved in fusion research is as well. However, on page 67 we have this: “Fusion neutron yield Yn : 10^6 for PF400-J to 10^11 for PF1000.” So I’m a bit confused.

    The key part is “thermo.” Physicists skeptical of the ability of the DPF to scale up to higher fusion yields attribute the fusion reactions to high energy beams and not to a thermalized plasma–Note that there could be beams AND a thermalized plasma.

    It still works for me and seems to download the same paper as before… a file that is both smaller and rather different in content from the one that you link to.

    A coincidence in titles might be the explanation.
