Re: Another (Preliminary) Report on Anisotropy
I have always been interested in what the anisotropy in the fusor would look like. Glad to see people are are interested of taking measurements with their setups. The flux anisotropy as well as energy distributions at different angles with respect to the beams could give interesting insights into th...

Re: Columbus-1 Linear Pinch Fusion Success
Great work Mark! First neutrons is always exciting. It's cool to see a pulsed power device like this producing neutrons at an amateur level. Imagine what the pinch fusion physicists of the 50's and 60's would think if they saw this now! From my experience using the dosimeters in a pulsed neutron/gam...

Re: Spellman Power Supplies
Hello Emrys, -40KV @ 5ma should work well enough considering you have sensitive enough counters, or long enough runtimes for Bubble Dosimeters or activation foils to pick up a reasonable signal. I ran my fusor with a -50KV 5ma Hipotronics supply. In its early life I tried to keep my voltages lower t...

Re: Columbus-I Pinch Tube Build
Mark, Great effort, it is really cool seeing this project come along. I can say from experience working with high-yield pinches impurities have a massive effect on performance, even when dealing with MegaJoule machines, one thumbprint on an electrode, one manufacturer sending a wrong type of glass o...

Re: FAQ - Neutron Transport Simulation, Detector Calibration, and Shielding
Liam, Great work! It is good to see someone using Monte-Carlo simulations in the community. This a great example of using a Monte-Carlo for detector work. One can easily poor hours into such software trying to find optimum moderator configurations, mapping the flux of such systems, etc... I have nev...

Re: Joe Gayo's lab tour
Personally I doubt this Tritium, but I think it is rather some artifact of the rga. In other systems I have used an rga on (not fusors), I have seen the peak at 6 before when working with deuterium. Remember the rga is ionizing, so there is the possibility of D3 ions being created as well as some ot...

Re: Joe Gayo's lab tour
Does this reading corellate with the high count rate from the BF3 tube? If so then you may be seeing real counts. I think setting up both a bubble dosimeter along with another tube at a greater distance at the same parameters of voltage, current, and pressure and see if you get the same yield. If th...

Re: Joe Gayo's lab tour
I think there should be decent dead time in your system that can cause pulse-pileup, but I am unsure why that would make you have multiplying count rates. I think there are three places that will give you dead time, and measurements of these with an o-scope could help diagnose this issue: 1. Tube de...

Re: Some Beefy Power Supplies
Dennis, I believe the unit supplkies 25kHz which should be enough to drive a multiplier. Of course, the multiplier would have to consist of many stages to step up to 60kv. When I get around to taking o-scope measurements of the driver, ill begin looking into the values of the diodes and capacitors t...

Re: T-T Fusion in a radioluminescence tube.
The cross sections for Tritium-Tritium fusion are incredibly low, and I doubt it is in reach of an amateure, researcher, and I am highly suspect of the physics the video poster is claiming to be occurring. The proper use of radioactive materials, and including tritium exit signs and Americium from a...
