Measurement of turbulent electron temperature fluctuations on the ASDEX Upgrade tokamak using correlated Electron Cyclotron Emission

摘要

Much progress has been made over the past few decades in understanding and modelling the underlying turbulent mechanisms and gyro-kinetic modelling codes are now often able to reproduce experimental heat fluxes within error bars (see for example [1,2]). Validation of non-linear gyrokinetic code predictions against measurements of the underlying turbulent micro-structure, such as fluctuation amplitude, correlation length, fluctuation phase relations and spectral index, can serve to help refine and reduce turbulent transport models further.
