The effects of low energy (5 to 30 keV) electron precharging on the SGEMP response of several common satellite materials exposed to photons from an exploding wire radiator (EWR) are reported here. The EWR source produces a narrow ( 50-100 ns) fast risetime (10 ns) low photon energy (E 2 keV) pulse which results in low energy photoelectron emission. This EWR source has been used for previous SGEMP experiments on simple objects, on a structural model of the Skynet satellite and on a simple model of a resonant structure. EWR exposures of an electron precharged Skynet Qualification Modell satellite established that the SGEMP response was enhanced by precharging either the thermal paint or solar cell covers, and that on one occasion, a massive discharge of solar cell covers appeared to be triggered by the EWR exposure.
