Re: FAQ - Neutron Transport Simulation, Detector Calibration, and Shielding

This is awesome, awesome, awesome. I thought pretty much nobody else was interested in Monte Carlo methods. I tried to repeat Carl's work in the mid 2000's and had good agreement with the fast neutron flux, but my other results were weirdly off. I exchanged emails with him but couldn't work out the ...

Re: Neutron Flux Calculation

Richard has a recent reply in the new users area about this. The tube detects slow neutrons, so you need a calibration between detections in the exact setup you have (tube, moderator, bias, threshold) and the fast neutrons of the same energy that cause it. When you have a fast neutron flux reading y...

Re: Landscape

The best evidence is the fusor does not work that way.

The electric potential is the potential energy well.

Re: Inverter Microwave Oven circuit

Could the air gap be there to prevent the core saturating and the resultant current spike that might also kill the drivers?

Re: D+D Cross section?

<t>The maximum cross section does not corrispond to the maximum power output, or the maximum reaction rate, so on their own, I'm not convinced they help much.<br/> <br/> DT fusion cross section peaks about 100kev deuteron energy. DD peaks about 2 Mev.<br/> <br/> Carl,<br/> When I search for H-2 d,* ...

Re: Proton Discussion

<t>I think there is another chemistry point of view that also applies here. Reactions don't happen because the reactants are unstable, they happen because of the existance of a more stable state at the end.<br/> <br/> I do not think there is much milage in trying to explain neutron decay on the basi...

Re: Proton Discussion

IF the proton is complicated, then it is made up of smaller parts and therefore cannot be primary.

Re: New 1.5 Gigavolts device

I can't speak for anyone else, but the last time I used an electronics simulation package, it often produced garbage results. Like voltage multipliers that don't multiply, or ultra high frequency oscillations where no parasitic capacitors/inductors have been wired in...
