Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

Finite element analysis calculations are performed to determine the temperature profile in sections of the ITER Electron Cyclotron Heating (ECH) transmission line waveguide. Each aluminum, corrugated waveguide transmission line will transmit up to 1.5 MW of electromagnetic radiation over roughly 200 meters from a 170 GHz gyrotron to heat the plasma in the tokamak. The “ridged tube” waveguide has integral water cooling traces which are lined with copper tubing. Each transmission line includes miter bends which may be actively cooled and waveguide couplings, where the waveguide cannot be actively cooled due to coupling hardware. The amount of cooling water available is limited, so determining the required amount of water in the cooling lines is essential. Finite element computational analyses are performed to determine the effect of the heat load and water cooling on the temperature profile of the waveguide in various steady-state cases.
