Multiple diagnostic data analysis of density and temperature profiles in ASDEX Upgrade

摘要: A major challenge in nuclear fusion research is the coherent combination of measurements from heterogeneous diagnostics. Different measurement techniques for measuring same subset physical parameters provide complementary and redundant data for, e.g., improving reliability parameters, considering all dependencies within between diagnostics, resolving inconsistencies. Coherent means integration diagnostics raw including forward modeling instead results which frequently relies on cumbersome iterative procedures. The Integrated Data Analysis (IDA) approach provides a full probabilistic model statistical description an integrated set different IDA was applied to analyse combined Lithium beam (LIB), DCN interferometry, electron cyclotron emission (ECE), Thomson scattering (TS) at ASDEX Upgrade obtain density temperature profiles with temporal resolution up 50 μs spatial 5 mm plasma edge. Interdependencies are fully considered. enables us study fast evolution density, pressure inter-ELM phases as well ELM resolved [1].
