Hello all,
I mentioned previously that Noah and I had run out of deuterium. This is not the case. We thought that our lecture bottle's valve was open when it was actually closed. We simply used all of the deuterium stored in the regulator. This was a pleasant surprise. Anyway, we decided to fuse more atoms.
Data:
Voltage: 25-30 kV
Current: 9-10 mA
Deuterium pressure: 5-15 mTorr
Bubble dosimeter sensitivity: 29 bubbles/mrem
Bubble dosimeter distance from ideal neutron source: 15 cm
Bubbles generated: 24
Combined duration of testing: 20 minutes
Calculations:
Neutron radiation dose: 24 bubbles/29 bubbles/mrem = 0.83 mrem
Neutron energy: Mono-energetic 2.45 MeV (flux to dose rate = about 8 (neutrons/cm^2/second) / (mrem/hour))
Neutron flux at detector: (0.83 mrem) (1/3 hours^-1) (8 (neutrons/cm^2/second) / (mrem/hour)) = 20 neutrons/cm^2/second
Total neutron flux: (20 neutrons/cm^2/second) (4*pi*(15 cm)^2) = 58,000 neutrons/ second
We were able to capture the most star-like image yet!
Here is our bubble detector:

Re: More Fusion
That's the way it is done! Good work! It will get better quickly with running experience. I am using the same bottle of D2 for the past 8 years.

Fusion is the energy of the future....and it always will be
The more complex the idea put forward by the poor amateur, the more likely it will never see embodiment

Re: More Fusion
It's great when you have repeatability in a fusor! Then you are doing real science. One suggestion I would make regarding the design would be to locate the gate valve on the opposite side from the high voltage electrode for safety reasons. This way you don't accidentally touch it as you operate the valve!

Re: More Fusion
Very impressive! Thanks for both the pics and data!
