Fusor Forums

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...

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...

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...

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...

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...

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...

Hello All, I haven't been posting nearly as much as i want to, and that is, of course, because I have not been doing as much as I want to. Working two jobs and college turns to take up a lot of time. I am however, slowly pinging away at the upgrade to my fusor. In fact, this will be an entirely new ...

Neutron counts into the 1e7 range with a smaller chamber! Wow! I never though I would see it. This is a great system. It is cool to see that you are using software like FEMM to investigate your fields. It would be interesting to see plots of the E-field in your setup as well. After going back throug...

It would also be interesting to see the neutron and gamma pulse waveforms with a scintillator/pmt or perhaps some sort time-of-flight detectors. Of course that is easier said than done, but the waveforms of the radiation could tell you a lot, and with enough distance you could, based on timing of th...

This looks like a really interesting project. I noticed there isn't a current diagnostic mentioned or in the drawing. One way to look at and better diagnose the dynamics of the pinch is to use a rogowski coil to measure your current waveforms. The changes in current may help you better speculate wha...
