From what literature I've managed to scrounge, the supercritical liquid is commonly one of the dreaded chlorofluourocarbons (saw one paper where they used R-12), although I've seen references to hydrocarbons as simple as butane being used.

The idea's been brought up a couple times, and Rob Noulty at Bubble-Tech can point to some literature. I don't think anyone's done acoustic detection yet with the little PND dosimeters.

I am a student at the community college. I and our classmates are doing
a project about neutron. We don't have a lot of budget, so we can't
buy whatever we want. We need a bubble neutron detector, but we know the
company in Canada has a minimun order of $300. So, could you sell a
bubble neutron detector to us? We really need to finish the project.
Without that, we can't do anything.

Hummmmm very interesting indeed. I guess now I'll be purchasing different types of polymer gels and doing some testing. I think we can bust the formula and if not exactly even being able to get a rough neutron bubble formula would be worthwhile. If other are interested please include your interest. I don't yet have a neutron source but I can make up gels and sent them to Richard or someone else with a working source for testing. The more folks involved the more test we can run. I'd like to start with a list of possible polymers to try.

If there is interest I'll start a need thread to keep it off the FAQ.

It may be as simple as silica gel super saturated with heavy water. The neutron strikes producing tritium gas bubbles.

Question: How hard is this "GEL" ? Someone have any idea? Is it really soft or is it hard like silica gel?

Thought I'd give an update on the pricing of the bubble detectors sold by bubbletech. There is a minimum order of two at a price of $158 each. It costs an additional $56 in shipping/handling/border processing. All this comes down to a grand total of $372. Nice. Pretty steep price if you ask me.
