Further studies of ELF oscillations during electron-beam firings on Spacelab 1
Abstract
Injections from an electron beam that was part of the phenomena induced by charged particle beams experiment were observed by the space experiments with particle accelerators (SEPAC) 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).
