Apollo 14 ALSEP Electron and Proton Spectra, offline at NSSDC

ResourceID
spase://NASA/NumericalData/Apollo14-LM/CPLEE/PT19S

Description

The data are 19.2-s count rates of electrons and protons at several energy steps between 40 eV and 20 keV. Two electrostatic analyzers, each feeding 6 detectors, are oriented vertical from the lunar surface and 60 degrees from vertical, towards lunar west.

Name
Count rates
Description

Count rates of electrons and protons from each of two electrostatic analyzers, each of six detectors per analyzer, and each of 8 voltage steps for each 19.2 sec cycle

Caveats
Occasionally (rarely?), the instrument was operated in a manual mode, when the cycle was 2.4 sec and voltages were not swept.
