NAME Apollo 15 ALSEP ARCSAV SIDE/CCIG Raw Cleaned ASCII Data Collection (1975-092 to 1975-181)
TYPE Data
DESCRIPTION This collection contains fixed-width ASCII files of daily raw cleaned science and engineering measurements acquired by the Suprathermal Ion Detector Experiment (SIDE) and the Cold Cathode Ion Gage Experiment (CCIG; also known as the Cold Cathode Gage Experiment for the time span of 02 April through 30 June 1975. These data were extracted from NASA's original Apollo Lunar Surface Experiments Package (ALSEP) archive tapes, also known as ARCSAV tapes, that recorded 24-hour, time-edited, and rearranged raw binary data transmitted from the Moon. The extracted binary data were corrected for obvious tape read errors then transformed to ASCII format for this archive. This collection also includes one ASCII file of SIDE/CCIG-related command verification data extracted from the ARCSAV binary files.

PRIMARY RESULT DESCRIPTION Measurements of the differential energy spectrum of positive ions having energies from 0.2 to 48.6 eV per unit charge and 10 to 3500 eV per unit charge as acquired, respectively, by the mass analyzer detector and the total ion detector of the Apollo 15 Suprathermal Ion Detector Experiment (SIDE); and measurements of density and temperature for pressures ranging from 10^-6 torr to 10^-12 torr as acquired by the Apollo 15 Cold Cathode Ion Gage (CCIG) experiment. The scientific objectives of these experiments were to measure the flux, number density, velocity and energy per unit charge of positive ions near the lunar surface, and to detect any lunar ambient atmospheric pressure. The time span for these data is 02 April through 30 June 1975.
