 note = {The VLF wave instruments on board Akebono (EXOS-D) were designed to investigate the propagation characteristics of ground-based VLF transmitter signals in the magnetosphere, the wave phenomena closely associated with energetic particle precipitation in the auroral zone, and the physics of wave-wave and wave-particle interaction phenomena. In order to investigate these features, it is important to measure the absolute electric and magnetic field intensities of the wave phenomena of interest in addition to the dynamic spectra. It is also essential to be able to determine the normal direction of the wave and the direction of the Poynting vectors for the phenomena. The VLF instruments cover a frequency range from a few Hz to 17.8kHz for electric and magnetic field components and are composed of the following subsystems : a wide band analyzer (WBA), mult-channel analyzers (MCA) Poynting flux analyzers (PFX), ELF frequency analyzers, and a vector impedance probe (VIP). The present report describes the characteristics of each subsystem briefly and introduces some preliminary results of the observations, such as an example of the wave normal direction of whistlers determined by PFX, a triggered emission generated from the Australian Omega signal, ion cyclotron emissions observed around the magnetic equatorial plane, and a typical vector impedance of the wire antenna., 資料番号: SA0166924000},
