“…Both wave and electron spectra change drastically when the satellite crosses the plasmapause which is indicated on the top of the top panel by a solid triangular mark accompanied by "P". The plasmapause position is determined by a VLF Doppler measurement (KIMURA and HASHIMOTO, 1981). Outside the plasmapause, high energy electron fluxes are enhanced compared with those observed inside the plasmapause.…”

“…Therefore the L shell of the plasmapause lay around 5.5 to 5.2 in the evening to midnight sector on that day. The plasmapause position was again identified by a change of antenna impedance monitored by a VLF Doppler (DPL) measurement (KIMURA and HASHIMOTO, 1981). Figure 9 shows a simultaneous presentation of both wave and electron spectra.…”

Case studies on correlation between VLF plasma waves and energetic electrons are presented based on data observed by EXOS-B satellite. The frequency range of the observed VLF plasma waves is from 150Hz to 9.5kHz, while the measured energy range of electrons is from 5eV to 11keV. Data observed on specific four passes (Revs. 185, 273, 284, and 588) are examined. Especially data on Rev. 284 are shown in detail because both the VLF waves and energetic electrons are observed continuously over more than 5hr on that orbit. It is shown that band-limited hiss and discrete VLF emissions below a local cyclotron frequency are well correlated with 1 to 10keV electrons.
