Cleaned things up somewhat, and got more beam out - going to keep dialing it in.

Robert,

Now this is a really cool project! I've watched this thread with great interest. Is the Northwest Nuclear Consortium open to visitors?

I'm trying to pull together a midwest conference for fusor.net members (viewtopic.php?f=47&t=11408). I know you are well outside the midwest but do you ever travel to this area? You would certainly be welcome as a guest speaker.

Thanks Garrett,

With regards to the invite out east, thanks also. I can't say I'm out there very often, but I'm likely to be at HEAS this year, I'll be certain to say hello if I see you there.

I haven't been affiliated with NWNC for several years, and admins haven't been responsive to my request to edit the thread of it's mention. The system resides with me now, as it should.

Understood. I was really interested in seeing your device first hand and discussing ideas. Hopefully I'll be at HEAS this year.

You're welcome to drop by Seattle sometime and see it, it's in my living room. Otherwise wait about a year and visit the Philippines as I'll be there studying abroad for a few years and my most of my hardware but for the most extreme of export restricted materials will come with. My couch there will be open to to surfing, unless I'm out surfing.

Robert,

Can you elaborate more on the physics of plasma going into "H" mode?

I have seen this phenomenon myself or at least something similar while playing around with an induction coil and a neon tube, as the neon tube was held close to a high frequency induction coil the tube lights up but at some point the plasma goes from being just normal "neon tube bright" to something more like a flash bulb. The transition was rapid, and within seconds it melted the glass and vented the neon tube.

Jake,

Thanks, read the abstract, but the rest of it is behind a pay wall, so it's inaccessible to me unless I pay $33.
