Ionospheric Modification Experiments( Book )

1 edition published in 1972 in English and held by 1 WorldCat member library worldwide

A set of experiments were performed in order to investigate certain aspects of the effects of heating the ionosphere by a high power transmitter. These experiments, based on analogous laboratory experiments, consisted in exciting the ionosphere by a variety of methods using the ITS 2-megawatt transmitter and then simultaneously quick-look analyzing the reflected waves using a spectrum analyzer and recording them on analog magnetic tape for subsequent data reduction and analysis. Experiments were performed to determine the nonlinear behavior of electrons under the pump excitation. (Author)
QUIPS: (Quiescent Uniform Ionized Plasma Studies). Modeling of the Auroral Electrojet by TRW Systems Group( Book )

1 edition published in 1974 in English and held by 1 WorldCat member library worldwide

A cylindrical device is constructed for modeling the electrojet instability. The plasma, which is collisional for ions and collisionless for electrons, is produced by two concentric rf exciter discharges in an axial magnetic field. Each exciter consists of two electrically floating concentric strips in a grounded cage. The plasma is confined axially at one end by the cage, at the other end by a segmented anode consisting of 18 concentric rings, and radially by grounded walls at large distances (d 7 or = lm). The anode rings are connected in series by resistors facilitating the imposition of a radial electric field which causes an azimuthal, closed, Hall current. The plasma density is uniform axially and azimuthally, and is controllable radially
Ionospheric Plasma Effects( Book )

1 edition published in 1975 in English and held by 1 WorldCat member library worldwide

During the first half of this contract, the following effects, related to ionospheric modification experiments were investigated: (1) Convective parametric amplification (improvement and exercise of a computer code yielding a theoretical parametric study of Arecibo spectral observations in qualitative agreement with measurements in restricted parameter domains); (2) Refraction by the pump of parametrically generated waves in both the laboratory and the ionosphere; (3) Double resonance excitation in a homogeneous plasma by infinite wavelength pumps in general and for laboratory and ionospheric applications in particular; and (4) Parametric instabilities driven by linearly converted pump modes
