Abstract

Measurements of the returning electron flux distribution in response to 8 keV, 10 to 100 mA, 20 to 40 ms electron beams of the PICPAB particle accelerator on board Spacelab-1 were performed by an electron spectrometer in the energy range from 0.1 to 12.5 keV (experiment 1ES019A). The electron flux followed almost immediately the beam within the sampling interval of 1 ms. A major flux increase was found at low energies, but also up to the beam energy. The effects of different beam currents and of payload charging are discussed.
