Description
A dual-frequency gyrotron is currently under development at UNIST to support future DEMO-relevant and innovative fusion reactors. The target frequencies, 142 GHz and 208 GHz, have been selected based on conceptual design requirements and the availability of existing laboratory resources. The conceptual design study of the gyrotron has been completed, and experimental activities to validate the design are underway. These experiments include testing a mode converter using mode generators for both frequencies, employing a novel alignment technique based on a machine learning algorithm [1]. With the full assembly of a demountable dual-frequency gyrotron, we will present recent experimental results and performance evaluations. Additionally, conceptual design studies on a remotely controlled transmission line and investigations into an OAM (orbital angular momentum) gyrotron will be discussed [2].
