Wave-Electron Resonance Mapping for Tokamak Plasmas

MATLAB code for parametric mapping of the electron-cyclotron resonance condition in tokamak plasmas, developed in the context of an Integrated Master's diploma thesis at the National Technical University of Athens (NTUA).

Overview

The repository contains a MATLAB implementation for scanning the electron-cyclotron resonance condition across prescribed tokamak geometry, plasma-profile, magnetic-field, launch-angle, and frequency settings, with resonance-root results written to CSV for downstream analysis.

Main capabilities

• radial scan or fixed-radius / q-surface evaluation
• selectable density-profile models
• parameter scans over theta, B0, phi, and frequency
• resonance-root solving inside a prescribed EC frequency band
• CSV export of resonance results
