Caption: A single electron forms a spiral track in the magnetic field of the 10-inch (25 cm) bubble chamber at the Lawrence Berkeley Laboratory, in California. As it loses energy in ionizing the liquid hydrogen which fills the bubble chamber, the electron becomes less & less resistant to the force of the magnetic field & therefore curls round more tightly. Electron spirals like this are a common feature of bubble chamber photographs. The yellow colour has been added photographically. Original is BW print A138/035.
