First Light Success

<t>Got first light this afternoon. The problem was indeed the spark plug pass through and it worked great after getting some straight-through plugs. Images were taken at 150 microns at voltages ranging from 100V to 3000V. Couldn't get any more out of my parallel NST transformers and will most likely...

NST Current Regulator

<t>I know most NST units have a current regulation system in them, I think it's usually called a magnetic shunt. Will this be sufficient to load the current meaning a ballast resistor isn't even needed and I can hook it straight up to a fusor? I know an NST isn't the optimal device for this but I wa...

Re: Why Is It Not Producing First Light?

<t>Here is a schematic<br/> <br/> The oil tank is not grounded at all since it is all floating due to the unfortunate nature of the transformers being center tapped. <br/> <br/> Can the two transformers be operated in series rather than parallel? I remember once reading that putting secondaries in s...

Re: Why Is It Not Producing First Light?

<t>I have a diffusion pump running behind a welch 1400 and it is definitely reading 0 microns. I thought the best vacuum possible was the best. Is this true when actually performing fusion but not for a glow discharge? I'll cut the diffusion on the next test.<br/> <br/> It has several grounding poin...

Re: Why Is It Not Producing First Light?

<r>Any ideas why this is happening? <br/> <br/> <URL url="http://www.youtube.com/watch?v=0gS0LmPf_N0">http://www.youtube.com/watch?v=0gS0LmPf_N0</URL><br/> <br/> Even with the grid disconnected, just the transformers and rectifiers operating do it. Is it just a lot of RF noise can actually cause tha...

Why Is It Not Producing First Light?

<t>We finished building the whole system today and attempted to get a first light. The problem is, it didn't. First we hooked it all up with a rectified 12kv 60ma neon sign transformer in oil since the chasis of each transformer is floating on the center tap voltage and got a reading of 15,000V DC u...

Re: Diffusion Pump Questions

<t>The need for liquid nitrogen for the trap should be correct. This trap operates by condensing any liquid vapors before they backflow into the chamber, so it has to be extremely cold to get this system going. A lot of times in a simple fusor a trap isn't always necesary, so perhaps you could get b...

Re: Deuterium Generator

Where would one get swagelok teflon ferrules? I see mentions of them on google but I can't find anywhere that sells them.
