@gg459 The He-3 detector was purchased many years ago from Don Orie at OE Technologies. Unfortunately, He-3 gas is in short supply and so the detectors are difficult to obtain now. You still probably have a number of other good options for what you're doing, however.
Hi, you said in your video that the Am241 source has 5mCi, which is very high, because normal smoke detectors have only 1µCi of radiation. Did you disassemble 5000 smoke detectors or do you have just very strong ones?
Did you leave the Am241 in in the "container" from the smoke detector or did you revomed the powder and poured it on the Be foil?
Thanks for all your videos, they are all very good and interesting
I think you've misheard a little - the source is known as "ambe" which is a mixture of Am-241 and Be - the Am241 is an alpha emitter and these alpha particles when they interact with Be or Li produce neutrons so the AmBe source is much more than a smoke detector which uses only Am241. I've access to a 1Ci AmBe but won't be mentioning on here where this is!!!! But the difference is the alphas emitted from Am-241 and the neutrons emitted from an AmBe source.
The total Am-241 activity in this source is 5.3 millicuries.
The source is composed of many sealed sources from antique smoke detectors aligned on ~40-mil beryllium metal foil. The individual sources remain intact and undamaged.
I don't share the exact brand and model of smoke detector that is preferential for this use, in order to protect my supply. However, the "secret" is well-known in the nuke hobby. They are very old technology, but still in use.
thanks! been reading about early particle physics, and watching that moderator in action was a blast.

where did you get this? I'm building a fusion reactor but have had some trouble finding a decent neutron detector
