Cosmic-Ray Detector

NSSDCA ID: 1972-031C-07

Mission Name: Apollo 16 Lunar Module /ALSEP
Principal Investigator:Dr. Robert L. Fleischer


This Apollo 16C experiment was designed to measure the charge, mass, and energy spectrum of solar wind and heavy cosmic rays in the energy ranges from 0.5 to 10 keV/nucleon and from 0.2 to 200 MeV/nucleon, to provide calibration data for glass detectors including tektite glass, to measure the thermal neutron flux at the lunar surface, and to assess the problem of argon 40 implantation. The experiment shield mechanism failed to retract completely, thus obscuring the field of view of the detector.
