The theory of cosmic-ray scintillations has developed rapidly over the past few years. Cosmic-ray scintillations arise from various irregularities in the magnetic fields through which cosmic-ray particles must travel before being observed. These scintillations are characterized by broad-band fluctuations in intensity over time. We have undertaken a study of the cosmic-ray background as observed with the Rice University Suprathermal Ion Detector Experimental (SIDE) that was deployed on the lunar surface during the Apollo 14 mission. The energy threshold for cosmic-ray protons was approximately 25 MeV in one sensor and 50 MeV in another. We find that the interplanetary cosmic-ray scintillations are observed with the SIDE and these observations are consistent with current theoretical models and with other experimental results.
