An active expriments with electron gun on the microsatellite
Abstract
Plasma radio emission in the presence of energetic particle fluxes is a very informative source of knowledge about plasma processes and its parameters in the interaction region. Now there is a big experience of work with election beams in the Earth ionosphere. The new generation of spacecrafts- micro and small satellites give us rather chip possibilities to carry out space orbital experiments. But there is an obstacle to do an active experiments at microsatellite with injection of electron beam-the limited onboard power source. Typically it requires at least tens of Watts to heat the cathode of electron gun and to accelerate the electrons of the beam. The proposal is made to apply ``solar'' electron gun with ``zero'' consumption from satellite powersuppliment. Such type of electron gun could be applied for space experiments at near Earth orbits and for solar or planetary missions.
