Re: 3-D Model of a Stellarator Plasma

I can cast the negative view with ease as past evidence of mankind, his works and his progress tend to flow that way. Plus, I have no skin in the game. (no children to worry over) I do wonder for those who have children. What will their world will be like and even their children's children. I am not...

Re: 3-D Model of a Stellarator Plasma

Models and test runs in the mathematical virtual world mean something only to those who create them. The real world does its thing without caring about models or virtual successful runs. Until something like the stellarator or ITER or a good cold fusion experiment creates over unity fusion energy, t...

Re: Diy high voltage probe

Of course the quantity of resistors can make this make up capable of 20 watt or 40 watt dissapation handling easily a 1 ma current. the DVM will not demand a tiny fraction of 1 ma. The key factor is that at least 1/4 watt resistors would be needed for the 500 volts across each one at 40kv. Film resi...

Re: Grid stem ...plasma where it shouldn't be

This is probably cross related. spheres and long cylinders tend no to see this issue. I have no doubt, you will work it out.

Re: NEW Fusor V build under way.

The window is 100% opaque to any visible light whatsoever, period! It might as well be made of stainless steel. It is not a #10 density filter it is worse than that. Intense IR is all that will penetrate. A the windo is of no real use, I will leave this sleeping dog lie until after the HEAS gatherin...

He has a rem ball. The white sphere.

Ameen you are now in the neutron club. Thanks for the fine images and data. You system is a good example of what can be done by slow stepping your way through each system victory.

Re: NEW Fusor V build under way.

No! Actually it has only been in use as a brand new window as of the first post in this thread, 7/10/20. Look at the colorful, full image in the post of 7/11. I have been driving this iteration very hard. Again, only the fact that the video camera is sensitive in the IR that I see only the snow whit...

Re: NEW Fusor V build under way.

As I continue to run fusor V every day or every other day, my viewport is virtually opaque to visible light. NO color. NO central star. Only the IR seen from the glowing grid is seen on the monitor. I have about 4 other replacement viewports. I wonder if it is worth replacing it for the HEAS October...

Re: Grid stem ...plasma where it shouldn't be

Very interesting image. I am glad you got the plasma to be in the right place. See you in a couple of weeks, Jim.

Re: IR / Visible ZnSe windows

I once paid $100 for a giant (12" aperture) IR lens at a hamfest. It was undoubtedly some sort of military surplus IR lensing system. The lens weighed over 32 lbs! It had a totally opaque front element of pure elemental germanium. I kept it for about 3 years and sold it to a much more astute person ...
