Hello from California

... I am relatively new to the field, but I've been reading the FAQs and other posts trying to learn as much as I can, especially about high voltage safety and building my own vacuum chamber.

Re: Neutron Attenuation Discrepency

... and trying to determine actual neutron flux. Read that post just written in the neutron & radiation forum section. Frankly, your own in-house safety people will provide you all the details you need (how could they not?) and also, should have calibrated detectors for neutrons - I'm lost why ...

Re: Fusors and Maxwell's Equations

... fusor at a school - either a student or teacher. First and foremost, don't call a demo fusor project by that name. As soon as anyone in admin or safety googles that word, then nuclear fusion, neutrons and possibly x-rays source will appear. That will set off red flags. Call the device by what ...

Re: Tyler's Demo Fusor

... out, add a gas leak value to the system so that you can hold the pressure (say, 30 microns) so your plasma stays light. Good you are wearing safety glasses but that doesn't protect your face. A thin walled glass like that is just waiting to implode. At least upgrade to a thick walled wine ...

Re: Tyler's Demo Fusor

Rich and Dennis, thank you for your comments. I do wear safety glasses when working in the shop and lab. I have a procedure I follow when I operate my demo fusor’s power supply. After each run the variac is set to zero, I turn off the power strip, and ...

... plug, a variac, a microwave oven transformer, and a 20K ohm ballast resistor. I put the pickle jar vacuum chamber in a clear plastic trashcan for safety. Below are some pictures of my build, and my demo fusor making plasma. Tyler

Re: Construction of Neutron Grade Fusor

I see you are working hard. So, don't let safety slip by rushing. As for the final data you have posted, I'm a bit confused. Your moderated reading is 4.0 neutrons/sec and your non-moderated is 11.3 neutrons/sec. Yet when the detector has no moderator, ...

Since the distance was approximately the same in the two cases my comment does not apply. One thing others might not have noticed is that you ...

Re: Construction of Neutron Grade Fusor

... you need to be safe but kicking the voltage up to the 35 - 40 kV and using distance (and please, no holding the neutron detector) will provide safety (and again, do not sit so the lower body gets x-rays!) A simple metal stand is far too easy to construct so the detector can be held fixed in ...
