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.

A bit more on the polymer gels

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?
