Summary

The effects of grid transparency, photoemission, and secondary emission on the currents measured by an ion-electron collector experiment flown on OGO I are examined in detail. The calculated grid transparencies agree with laboratory tests. The measured photocurrents as a function of angle of incidence i agree reasonably well with the calculated current assuming the yield is proportional to (cos i + sec i). Equations are derived for the effects or secondary emission on the background currents caused by particles with energies greater than 30 eV, from which the fluxes and yields may be at times be calculated. The energies of the primaries can be estimated from the calculated secondary yields.
