Re: My hope for a power supply

“Intermittent duty up to 3kV output at half an amp with 75VAC 20A input at 25KHZ. Constant duty about 1/4 that." This is probably from a dental x-ray unit. These are designed to run for a fraction of a second at a time and so the intermittent duty rating. Fusor usage will require constant output. Wh...

Re: Anode Layer Ion Source Mod?

5W- hadn't thought of it in those terms yet. About the equivalent of a turn signal bulb in a Buick.
If I recall, I started getting some intermittent arcing when I tried to go over 2kv. Don't think the little alumina insulators would care for 60kv let alone 100! ;)

Re: New neutron detector available

"Price is reasonable. I can't give a number since I got my quote for a business,"
Since no price is listed on the website, what was the quote they gave you?

"Solutions of LiF were painted on the silicon surface "
What would one use to make a solution of LiF?

Re: Anode Layer Ion Source Mod?

The shop had already drilled the base plate, etc., so I stuck with my original plan. Now that it's been fired up, the 4th hole doesn't appear to affect it like you said. My source is at about 1kv, 5 ma, and 5 mTorr in the pics. Still playing with settings. No Viton o-ring installed yet. Can't feel a...

Re: Anode Layer Ion Source Mod?

Got it all. Thanks. May have given the wrong impression. Took the flange to the weld shop to have the holes drilled and tapped- no welding. Not a big fan of working on SS. Main problem is probably cheap drill bits and lack of enough lubrication in the past. Ordered a few different size Viton O-rings...

Re: Anode Layer Ion Source Mod?

I thought an o-ring would get too hot there. I'll have to find the right size and try that first. Lot less permanent than welding it. In light of that, I already have an extra CF blank that I'll use for the base. Took it to the weld shop this a.m. I noticed a long time ago it looked like it would si...

Anode Layer Ion Source Mod?

hjuklghjk 002.JPG One of Andrew's ion sources arrived here Friday. Got to thinking exactly how I was going to mount this. What if it was mounted/welded directly to the front of a CF or NW nipple? In the photo, the weld would fill the gap between the ion source and the inside of the CF nipple. This ...

Re: FAQ - Why is fusion so difficult?

"We have been able to create a momentary fusion reaction in the hydrogen bomb."

Even this requires a fission bomb/explosion as an inherent part of triggering the hydrogen bomb. The fission bomb itself is large enough to destroy a small city.

Re: George Ressinger Fusion Club

Have to agree with John and Richard. Bubbles don't look right. The bubbles I've generated in my own detector from a nuclespot and Be neutron source look just like these: i.ytimg.com/vi/RmyyEKjbofg/hqdefault.jpg You could replicate the fusion run- except use an air plasma instead of D2. Put the detec...

Re: Mass production anode layer ion sources for sale

That's enough for quite a few sources while only several of us agreed to buy one. Are you going into mass production or building a reactor with 100 ion guns? ;)
