Abstract
Injections from an electron beam that was part of the PICPAB (phenomena induced by charged particle beams) experiment were observed by the SEPAC (space experiments with particle accelerators) plasma diagnostic package. In particular, extremely-low-frequency (ELF) oscillations from 150 to 200 Hz were seen in the SEPAC Langmuir probe current. The strongest oscillations occurred when the ambient pressure was augmented by neutral gas releases from the SEPAC plasma accelerator (the magnetoplasma dynamic arcjet, or MPD)
