I'm a latecomer too. Here's the later incarnation of Oriani/SPAWAR lenr experiment: http://pages.csam.montclair.edu/~kowalski/cf/368project.html http://pages.csam.montclair.edu/~kowalski/cf/368TGP_oriani.pdf The goal is to make a "science fair" CF experiment which always works. He's etching CR-39 dosimeter plastic after placing it against a wire cathode in a simple electrolysis cell. But the hot alkaline electrolyte trapped in the cathode boundary layer attacks the dosimeter surface, so another layer needs to be interposed, but must be thin enough to not significantly block all the slow alphas/neutrons/weirdness. Oriani used 6u PC film, so that's what we're looking for. Thinner film might not survive the alkaline liquid. Only about a square inch is needed for each run. Ludwik just tried the 13u Kapton, and found that the film adjacent to the cathode wire is eaten away during the 4-day run. The 6u Mylar did this too, but the hole was smaller.

Or shake it and listen to the peak frequency of the pink noise? ;) Also, our Kapton tape displays that same "impossible" effect discussed years ago: the whole spool shows a positive charge, and Kapton pulled off the spool is strongly positive (even if I pull off a couple of meters, so it's not just the outer layer getting charged through hand contact.)
