DEVELOPMENT OF A PLASMA-FLUCTUATIONDIAGNOSTIC

THIS PROJECT ADDRESSES THE NEED FOR A SOFTWARE TOOL AVALABLE TO THE ENTIREE MAGNETI FUSION ENERGY OMMUNITY THAT CAN BE USED TO ANALYZE AND INTERPRET NONLINEAR FLUCTUATION DATA GENERATED BY A WIDE VARETY OF PLASMA DIAGNOSTICS. THIS SOFTWARE TOOL WILL BE DIVIDED INTO TWO BASIC PARTS: MATHEMATICAL/STATISTICAL PROGRAMS AND APPLICATION PROGRAMS. THESE WILL BE FURTHER SUBDIVIDED INTO THOSE SUITABLE FOR STATIONARY AND NONSTATINARY DATA. THE STATIONARY DATA PACKAGE WILL INCLUDE CLASSICAL POWER SPECTRA AS WELL AS BISPECTRA, THE LATTER BEING AN EXTREMELY POWERFUL TOOL IN THE ANALYSIS OF NONLINEAR DATA. THE NONSTATIONARY DATA PACKAGE WILL BE BASED UPON DIGITAL COMPLEX DEMODULATION AND TIME-VARYING SPECTRA CONCEPTS. APPLICATION PROGRAMS WILL INCLUDE FLUCTUATION-INDUCED PARTICLE TRANSPORT; S(K,W), AND DERIVATIVE QUANTITIES, SUCH AS TE STATISTICAL DISPERSION RELATION; THREE-WAVE COUPLING COEFFICIENTS AND ENERGY CASCADNG; AND NONLINEAR DIGITAL FILTEERS INCLUDING NONLINEAR ADAPTIVE FILTERS.
