Device to detect nuclear Energy dispersion through matter or space. In atomic physics.... The spark chamber is made up for example of a number of metal plates arranged in parallel with a voltage of some thousand volts between each other. The spaces between the plates are filled with gas. The Any radiation which directly or indirectly ionizes, e.g. alp... leads to spark formation between the plates along the path of Energy dispersion through matter or space. In atomic physics... through the chamber. The spark trace can be registered photographically or electronically.
