Diy Neutron detector tube

This area is for discussions involving any fusion related radiation metrology issues. Neutrons are the key signature of fusion, but other radiations are of interest to the amateur fusioneer as well.

This my first list of trial gases by next week starting
This list of very easy to find gases

Here is my list of gases for first trial:
1. Oxygen (O2)
2. Nitrogen (N2)
3. Helium (He)
4. Argon (Ar):
5. Carbon dioxide (CO2)
6. Acetylene (C2H2)
7. Propane (C3H8)
8. Butane (C4H10)
9. Nitrous oxide (N2O)
10. Cl gas
11. Sulfur dioxide
12. Neon
13. Hydrogen
14. Hexafluoroethane
15. trifluoroethane
. Still working on the list

Yay for experimenting.

It's important to restrict some variables, or let the sequence be guided by on-going results.
To test every gas in your list at 10 different absolute pressures, and 10 different voltages,
even with a single radioisotope source and moderator configuration, would be 1500 runs.
We await your first counts of any kind of radiation.

For the real easy to find gases, don't forget:
* air
* natural gas

Beware that ordinary commercial propane (LP gas) and butane are hydrocarbon mixtures with specified BP ranges, plus odorant. I think refrigerant grade hydrocarbons (R-290 and R-600a) are "technically pure" chemicals. In recent news, somebody blew up their house while performing a botanical extraction using butane, either n- or iso.
