The United States is developing the technology for shattered pellet injection, the key element of ITER’s disruption mitigation system. The system’s purpose is to protect plasma-facing components from heat and other forces that arise during a plasma current disruption event.
The disruption mitigation system has three functions: 1) limiting the electromagnetic force impacts of plasma current decay on components, 2) limiting the magnitude of heat and particle flux to plasma facing components, and 3) suppressing the formation of (or aiding in the dissipation of) a runaway electron beam.
