Caption: Cosmic ray experiment, 1932. Cosmic rays are energetic particles in space, detected by the shower of high-energy particles produced when they impact the atmosphere. This is a manually operated cosmic ray meter used in the 1932 expedition to Alaska and the western United States. One of the members of the expedition was the US physicist Ralph Decker Bennett (c.1900-1994), who at the time was a researcher at the Massachusetts Institute of Technology, USA. He was a co-author of the 1932 paper titled 'Intensity of Cosmic-Ray Ionization in Western North America', published in Physical Review, volume 42.
