Description
Electron beams have the potential to play a major role in future space-based experiments. These can range from investigation of the Earth’s magnetic field, to helping mitigate the effects of increased solar activity (e.g. by helping drain the Earth’s radiation belts of charged particles), to deep-space missions. An electron source on a space mission needs to be able to withstand the challenging environment of a space mission, including the shock and vibration of a launch, the radiation from space, and the temperature swings. In addition, an electron beam source needs to have low SWAP (size, weight and power), and be as simple and reliable as possible. Here we will describe recent efforts at Los Alamos National Laboratory to develop this electron source and show results of shock and vibration tests on both cathodes and electron guns.
