Good observation Chris! I note interesting bursts on my 3He tubes here, and no way is the pressure affecting the tube itself (or the geiger counters and other things). Makes a bit of sense since the hottest showers are actually under a little more mass than air -- about a few inches more thickness of some solid gets more cosmic showers under it than "nothing" + air does. My guess on the tubes is that not only does a hot enough charged particle from a cosmic trigger it, but they probably also knock real neutrons out of the moderator as well, which get counted the normal way.
I think despite Charles' superior technique with ion chambers and very low currents he's going to wind up with having to have a control chamber to get real useful numbers out of it.
And I'd be doing that no matter my faith in the detection media anyway, based on flukey things I've seen in the past. The background noise variability is just too high to get by without that.
