Nuclear Emulsion

NSSDCA ID: 1960-018A-01

Mission Name: Discoverer 18
Principal Investigator:Mr. Robert C. Filz


Two groups of films coated with nuclear emulsions, arranged horizontally and vertically, were used to measure the intensity and direction of cosmic radiation and to distinguish among electrons, protons, and heavier charged particles. These emulsions were sensitive to neutrons, x-rays, and gamma rays. Nuclear track plates were also included in the experiment package. Neutron density was measured by changes induced in a metallic bismuth detector. The experiment was contained in the recovery capsule, which was retrieved in mid-air after 48 orbits.
