Design

Robust operation of the ITER Electron Cyclotron (EC) system, including avoidance of damage to launcher and in-vessel components, is essential to achieve ITER’s mission goals. The main purpose of the system is to provide EC heating (ECH) and current drive (ECCD) to heat and control the plasma in order to enhance its performance and ensure its stability. ECH/ECCD is essential during ITER...

Technology

The dual-frequency gyrotron TH1510 [1] represents a collaborative achievement involving SPC, KIT and Thales, within the context of the TCV tokamak upgrade. SPC and KIT were involved in the gyrotron design, while Thales served as the manufacturer. The gyrotron is designed to generate a 1MW, 2seconds RF wave at 84 and 126 GHz, corresponding to the second and third harmonics of the tokamak...

45. The Optimisation of the STEP Heating and Current Drive System

Simon Freethy (UKAEA)

Design

For a reactor based on the Spherical Tokamak, it is very likely that the device will need to be completely non-inductive for the majority of the plasma ramp-up and steady-state phases, due to the limitations imposed on the central coil assemblies by the compact design. Efficiency gains from solenoid-driven current cannot be relied upon. What’s more, it’s critical that an electricity producing...

22. ECH Technology Developments for Future Fusion Pilot Plants at General Atomics

Technology

The world is preparing designs for various forms of Fusion Pilot Plants (FPPs) that will demonstrate electricity delivered to the grid from a fusion reactor for the first time. While electron cyclotron (EC) technology is a relatively mature fusion technology, there will still be need for advancement to economically generate electricity in a power plant setting.
