Cosmic Ray Spark Chamber: Photos and Information
I made this spark chamber for demonstrations in the early days of this millenium. I built it with the support of the Montana Space Grant Consortium, and it resided in the Museum of the Rockies in Bozeman, Montana until neglect got the better of it. I still (2021) get contacted occasionally by people wanting to build one, so I'll keep this page alive.
