Syntheic Diagnostics Platform for Fusion Plasmas
Authors: L. Shi
Abstract: A Synthetic Diagnostics Platform (SDP) for
fusion plasmas has been developed which provides state of the art
synthetic reflectometry, Beam Emission Spectroscopy, and Electron
Cyclotron Emission (ECE) diagnostics. Interfaces to the plasma
simulation codes GTC, XGC-1, GTS, and M3D-C1 are provided,
enabling detailed validation of these codes. In this paper, we
give an overview of SDP's capabilities, and introduce the
synthetic diagnostic modules. A recently developed synthetic ECE
Imaging module which self-consistently includes refraction,
diffraction, emission and absorption effects is discussed in
detail. Its capabilities are demonstrated on two model plasmas.
The importance of synthetic diagnostics in validation is shown by
applying the SDP to M3D-C1 output and comparing it with
measurements from an Edge Harmonic Oscillation mode on DIII-D.
