Beam-plasma interaction experiment has been done in the magnetosphere by emitting an electron beam (100 ～ 200 eV, 0.25 ～ 1.0 mA) from a Japanese scientific satellite "JIKIKEN". Various types of wave emissions are detected by a LF and HF wave detector (NPW(A)). Two waves near at upper-hybrid frequency and at electron cyclotron frequency, respectively, are detected in a low L-value region. In a higher L- value region, a harmonic generation of 16kHz is conspicuous, which is originated from the cathode heater power supply. The time variation and dependence on various parameters of the magnetosphere are studied.
