... Research . Projects . ... The name of the project APEX is a reduction from words " Active Plasma Experiments " . The core of the project are active experiments with injection of electron and (or) plasma beams from a board of the satellite with simultaneous registration of the phenomena, produced by interaction of injected beam with background plasma. ... Active experiments utilise modulated electron beam accelerator and source of modulated xenon plasma beam on the main spacecraft APEX. ...
