Nice. Can't wait to see those bubbles.

Congratulations! It is a very nice and compact setup.

Thanks.

4-6 weeks will be a long wait for the bubble dosimeter, but worth it.

Really nice setup man! You must have worked hard and long. I'm sure if you live close to a large city that there are calibration services or people on this form who are willing to calibrate with you. Good luck on your efforts, but judging how well this system is, I don't think your going to need it.

Do you really need a BD? I know it is a positive proof, but I believe (I am not an expert) you can already claim that you produced neutrons in a fusor, and be part of the Neutron Club.

I would rather wait until my setup is calibrated. I have a high degree of confidence that neutrons are being generated but an exact quantity (+/-20%) is more satisfying. In addition, I’m improving the signal processing of the neutron pulse in the meantime.

We, in the past have seen the Russian tubes mis-used, mis-calibrated and regularly detect the x-radiation from a fusor operating at 35kv and above.
The BD doesn't respond to X-rays at all, nor does a well worked, high pressure 3He tube or BF3 tube.

Boron lined tubes can also detect x-rays. Too many of the applicants have zero experience with electronics. Those who are proficient in electronics often have no experience with nuclear instrumentation. Those who do have a passing experience in nuclear detection electronics seem to have never constructed, worked on and tested a good, reliable neutron detection system.

The very fact we never get the classic test right out of the chute by electronic detection claimants explains a lot about their competence in neutron metrology. This gives rather constant pause to such first pass claims. We have explained this test over and over again but to no avail. It seems to zip right over the heads of all claimants.

I fear many do not read at all or to not read for comprehension or just read, understand and refuse to deliver. One of the great mysteries here.

Richard,

I assume you are talking about tests with and without the moderator, then with and without deuterium in order to eliminate x-rays and electronic noise respectively.
