AbstractElectron cyclotron waves have cutoff densities and cannot propagate in an over dense plasmasuch as NSTX These waves due to the mode conversion process in the upper hybrid resonancelayer reduce to electron Bernstein Waves EBWs which have no density limits Therefore theEBWs are suitable for plasma heating and current drive in over dense plasmas In this thesis themode conversion coefficient for X B process has been calculated For this purpose we havesolved Vlasov and Poison equations simultaneously The method which has used to solve Vlasovequation is Fourrier transformation The motivation for using this method is that the solution ofVlasov equation in phase space becomes so oscillatory and it is impossible to be represented on afixed numerical grid The important problem in studying the mode conversion process iscalculation of the maximum value for mode conversion coefficient that is very sensitive toplasma density fluctuation at UHR layer This sensitivity is seen in the Budden parameter scalelength Ln at UHR layer In order to complete mode conversion fitting the density scale lengthis very important Results of the plasma simulation in NSTX shows that for Bt 0 45 T andBp 0 15 T the mode conversion coefficient is maximum when Ln 2mm pdfMachine A pdf writer that produces quality PDF files with ease Produce quality PDF files in seconds and preserve the integrity of your original documents Compatible across nearly all Windows platforms simply open the document you want to convert click print select the Broadgun pdfMachine printer and that s it Get yours now
