“Louvers” on the SPARC Fusion Device Should Exhaust Gases as Hot as a Star (IMAGE)
Caption
Left: geometry of the SPARC tokamak showing the pump volume and the “louver” actuator that restricts gas flow between the plasma and pumping chambers. Right: neutral gas pressure increases strongly with the louver closed.
