Advantages and Limitations of Microwave Diagnostics in ITER
Microwave diagnostics are widely applied to study the parameters of, in particular, the electron distribution in magnetically confined plasmas. Thanks to their high accuracy, their good spatial and temporal resolution as well as some other advantageous properties, microwave diagnostics are considered as candidate measuring techniques for a large number of different parameters of the ITER plasma, including many category I parameters for machine protection and performance control. Microwave techniques that appear on the list of ITER candidate diagnostics are electron cyclotron emission (ECE) and -absorption (ECA), reflectometry, interferometry, polarimetry and ion (collective) Thomson scattering.
