Doppler Model for Adiabatic Toroidal Compressor Driftwave Frequency Profiles.

摘要

Microwave and CO sub 2laser scattering experiments on ATC (Adiabatic Toroidal Compressor) Tokamak have shown that there exists a spectrum of fluctuations with parallel bar f parallel bar =parallel bar omega /2pi parallel bar less than or equal to 1MHz at wavelengths lambda approximately 0.28cm and with parallel bar f parallel bar less than or equal to 400kHz for lambda approximately 1cm. However, a typical maximum frequency calculated for given experimental density and temperature profiles is f less than or equal to 150kHz for the longer wavelengths and differs with the experimental results by roughly a factor of 2or 3. At shorter wavelengths the calculated maximum f is less than or equal to 100kHz,which differs quite substantially with the experimental result. This discrepancy is interpreted as evidence of vector E x vector B Doppler shift from a radial electric field. (ERA citation 03:013282)
