Abstract:

This report describes the suite of diagnostic instruments at a major facility for experimental radio science research, under development in Gakona, Alaska. This site is being developed as part of the High Frequency Active Auroral Research Program HAARP. A key objective of the program is the identification and characterization of the physical processes initiated in the ionosphere and space via interactions with high power radio waves. Among these phenomena are plasma instabilities and turbulence electron acceleration, including the production of optical and infrared IR emissions the generation, maintenance andor suppression of ionization structures aligned along the earths magnetic field the modulation of currents in the ionosphere, thereby producing virtual antennas in space to generate ULFELFVLF radio waves and the production of stimulated electromagnetic emissions SEE. The efficiencies that can be obtained in the initiation, maintenance, and control of such processes and techniques to excite selected individual processes, or to suppress unwanted ones, are also research areas of increasing interest. To provide the experimental capabilities required to meet its objectives, the HAARP Gakona facility includes a powerful, phased-array, high-frequency HF transmitter and an extensive complement of radio-frequency and optical diagnostic instruments.
