Using the Stix finite element RF code to investigate operation optimization of the ICRF antenna on Alcator C-Mod Open
As the Ion Cyclotron Radio Frequency range (ICRF) heating becomes more favorable in fusion devices, the urgency of predicting and mitigating impurity generation that arises from it becomes more pressing. In the ICRF regime, rectified Radio…
