Abstract:

The CHARGE-2B sounding rocket was launched from Poker Flats Research Range, Alaska, in March 1992 to investigate VLF electromagnetic radiation generated by a modulated electron beam in the ionosphere. A Langmuir probe on board the Rome Laboratory Diagnostic Free Flyer DFF sub-payload was the only source of local electron density and temperature data for the mission. The probe detected supra-thermal electrons generated by the beam injections. These observations were used to characterize the disturbed plasma region surrounding the beam-vehicle system. Spectral analysis of the probe current data reveals a low level of electron density fluctuation despite clear signatures of electrostatic beam emissions on the DFF wave observations.
