Re: 1D Cathode with Neutron Run

Jim, You should read this document. Its linked in the FAQ somewhere, but google works too.

[The design and optimization of an inertial electrostatic confinement fusion device]
by Hermans, E.C.G.

It outlines the entire fusion system quite well.

Re: Photography of Plasma and Glow Discharge

As luck would have it my iPhone XS Max takes great pictures through the viewport. GoPro (worthless, because the XRays and EM Noise make it go nuts. Maybe shielding?) Fancy industrial camera (Crap) -> But maybe a better/different one would work if one was to keep trying Cheap backup camera (works pre...

Re: SmCo Grid for Deuteron Deflection

Mr Feldman; sure I will check your numbers... I get 1.61 Inches. ...but pretty close to 2. Magnetic forces apply a centripetal force F=mv^2/r. Then F=qvB qvB=(mv^2)/r r=mv/qB v=Speed m=Mass q=Charge B=Magnetic field strength Static: Deuterium Mass: 3.35E-27 Deuterium Charge: 1.60E-19 Voltage: 40kV B...

Re: SmCo Grid for Deuteron Deflection

Yes, 1% is not "near" C, however its way too fast for a magnet to have much affect. I had to make a quick XLS on this, as I recalled it being around 50% of C, but that was an electron at 40keV. I stand corrected. Correction: I used the mass of a proton, obviously the Deuteron is just over 2x the mas...

Re: Calibrating a Neutron Detector With Background Neutrons

Thank you for sharing this. I have spent the better part of 3 years researching, scouring, and purchasing neutron detection hardware. A. Somehow I had missed the CT007-T neutron detector, likely because it has not yet been released. They dont disclose the technology. My guess is LiI(Eu) or CLYC. B. ...

Re: SmCo Grid for Deuteron Deflection

The concept wont work, but you should still do it as you will learn a lot. Major scientific advancements were the end result of experimentation without merit. Heck Nikola Tesla did not even believe in electrons! 1. Your SmCo will get very hot very quickly and will reach the point where its dipoles c...

Re: Fusor grid material

Yes. We have made many successful cathodes out of tungsten welding rods. Most in the 1mm diameter realm. Buy several from several sources. Some are fragile like glass rods, break no bend. Some bend fine. Use those. I have dropped a glass like tungsten cathode that took a day to make and had it shatt...

1D Cathode with Neutron Run

I do not post nearly as much as my research warrants. This is because sometimes I dont have a particular breakthrough and the specific tests are not really adding much to the forum. Let me define research: Its includes things I do in my lab that interest me, usually a manifestation of "I wonder what...

Re: "Blown up Sir!!" - OOPS....

Great job repairing your supply and glad it was a simple low cost/effort fix. However the part that really impressed me is that your fusor has been sealed for 9+ years!!

Re: Spellman DXM70N600X3547 power supplies on ebay -70kV 8.56MA

I bought (eBay) and repaired another one of these nice supplies. This was my longest repair as I needed two Mouser orders which take a few days and it really was a difficult troubleshoot. As I dont need the supply, nor was it financially expensive, it was really just for fun. As entertainment it was...
