Radar studies of mid-latitude ionospheric plasma drifts
We use incoherent scatter radar measurements from Millstone Hill and Saint Santin to study the midlatitude F region electrodynamic plasma drifts during geomagnetically quiet and active periods. We present initially a local time, season, and solar flux dependent analytical model of the quiet time zonal and meridional ExB drifts over these stations. We discuss, for the first time, the Saint Santi...
متن کاملObservation of fast stochastic ion heating by drift waves.
Anomalously fast ion heating has been observed in the Caltech Encore tokamak [ Phys. Rev. Lett. 59, 1436 ( 1987) 1, with the use of laser-induced fluorescence. This heating was found to be independent of electron temperature, but was well correlated with the presence of largeamplitude drift-Alfven waves. Evidence is presented that suggests that the heating is stochastic and occurs when the ion ...
متن کاملDirect Observations of Coherent Backscatter of Radar Waves in Precipitation
In previous work, it was argued that a source of radar coherent scatter occurs in the direction perpendicular to the direction of wave propagation because of the presence of grids of enhanced particle concentrations with spatial periodicities in resonance with the radar wavelength. While convincing, the evidence thus far has been indirect. In this work the authors now present direct observation...
متن کاملFast Compressional Alfven Waves in a Tokamak
Enhancement of cyclotron damping is theoretically evaluated based upon the wave E-field polarization which is modified by the two-ion hybrid resonance. The degree of enhancement and its asymmetry about the plasma center is consistent with experimental observations. The enhancement factor is very large at low plasma densities at which most of the past damping strength measurements have been repo...
متن کاملULF waves with drift resonance and drift-bounce resonance energy sources as observed in artificially-induced HF radar backscatter
HF radar backscatter which has been artificiallyinduced by a high power RF facility such as the EISCAT heater at Tromsø has been demonstrated to provide ionospheric electric field data of unprecedented temporal resolution and accuracy. Here such data are used to investigate ULF wave processes observed by the CUTLASS HF radars. Within a short period of time during a single four hour experiment t...
