ASPI experiment: measurements of fields and waves on board the INTERBALL-1 spacecraft
The plasma-wave experiment ASPI (analysis of spectra of plasma waves and instabilities) on board the INTERBALL spacecraft is a 1211 combined wave diagnostics experiment.It performs measurements of the DC and AC magnetic field vector by flux-gate and search-coil sensors, the DC and AC electric field vector by Langmuir double probes and the plasma cu
