Ion chamber used by Millikan
Abstract
See Phys. Rev. 31:921(1928). This instrument is not quite the same as that descirbed in this reference, but nearly so. In 1991 Dr. Victor Neher dated this piece in the 1930s. Said it was used on shipboard and on flights by National Geographic and Army Air Corps out of SD, went up to 60,000 ft. A similar instrument was made for Nishina and was used to measure radiation in Hiroshima after the A-bomb blast. The spherical part is the electroscope; the other components are a film chamber (for 100” of movie film), a clockwork, and a barometer. Mfg. CIT Physics Shop.
