Oh yes. It’s excellent.

But, as it’s often the case when learning … every answer rises more questions 🙁 So I cannot help myself asking those that occurred to me while reading that Saw+Lee paper:

1. is it not a mistake, that under figure.2 they state: it shows setup results with additional inductance of 33uH … which is gigantic with respect to intrinsic device inductances in the range of 33nH?

2. They say, that for a variety of devices, there is always an “optimal” inductance, where current reaches maximum. And that reducing inductance further does not increase discharge current (and they’ve published that observation earlier). I don’t have an access to that their earlier paper, but …. I was wondering if that effect can also have something to do with sin effects. In particular, one of the LPP devices reportedly had cathode rods fi=10mm, while at the frequencies equivalent to speed of the discharge (e.i. c.a. 20micro-sec), copper effectively conducts only at depths of c.a. 2mm. So having cathodes build from copper bars of 3mm/30mm cross section should do better. shouldn’t it?

3. Saw+Lee describe setups pinching current in pure D2, and measurement of D+D reactions which yield neutrons. Are there papers presenting special/angular distribution of resulting neutron outbursts? As opposed to ion jets from H+B reaction, neutrons could expose something regarding the internal dynamics of plasmoid vortexes. I think.

4. and last and the most important for me question: I cannot find any hints on why exactly the sheath forms at bottom of cathodes along the pyrex insulator, and not at their tops, where electric field between anode and cathode is the strongest. Where should I look for that answer??

So I’d really appreciate any further pointers to published results? (the links three posts above are probably interesting, but as they are mainly raw data, it’ll take me more time to really digest them)

But thenx anyway,
