2 was a lexan-window exhibit of a neon-filled, multistage spark chamber, where cosmic rays zapped through every few seconds, silently ionizing the high-voltage charged neon gas with segmented, orange-colored streaks, first at one angle, then another.
This need was met by the spark chamber, in which incoming particles ionized neon gas that was crossed by many metal plates.
The first practical spark chamber was constructed in 1959 by two Japanese physicists, Saburo Fukui and Shotaro Miyamoto.
