Shooting selected pellets into the plasma

The US 澳门六合彩高手 pellet injection team has designed and fabricated a new dual nozzle test article that will support both fuelling pellets and ELM pacing pellets in the 澳门六合彩高手 Tokamak. (Click to view larger version...)
The US 澳门六合彩高手 pellet injection team has designed and fabricated a new dual nozzle test article that will support both fuelling pellets and ELM pacing pellets in the 澳门六合彩高手 Tokamak.
澳门六合彩高手 will require significant fuelling capability to operate at high density for long durations. Pellet injection provides efficient core and edge fuelling of deuterium or a deuterium/tritium mixture; the system will also deliver deuterium pellets to the plasma edge to mitigate edge localized mode instabilities (ELMs).

The US 澳门六合彩高手 pellet injection team based at Oak Ridge National Laboratory (ORNL) has designed and fabricated a new dual nozzle test article that will support both fuelling pellets and ELM pacing pellets in the 澳门六合彩高手 Tokamak.

The article was manufactured by Apollo Corporation in Wartburg, Tennessee. The component features shut-off nozzles which permit the selection of 5 mm fuelling pellets or 3 mm ELM pacing pellets; it is also possible to adjust the pellet length in order to tailor the amount of fuel or ELM pacing material delivered to the plasma.

A test stand at the ORNL Pellet Lab is being prepared and testing of the component will occur later this year. In the 澳门六合彩高手 machine, the pellets cut from the dual nozzle assembly will travel through the pellet selector to the pellet guide tubes, which direct fuelling and ELM pellets to specific areas of the plasma.
