3D Printing water-cooled mirror components

The Korea Supercomputing Tokamak Advanced Research (KSTAR) facility contacted Bob Ellis of the Princeton Plasma Physics Laboratory (PPPL) to seek a design for a water-cooled mirror component. The component specified needed to withstand high intensity heat for up to 300 seconds during which it would be used to direct microwaves to heat plasma. The heated plasma would in turn fuel fusion reactions. Ellis utilized 3D printing to create a component consisting of copper and stainless steel with the cooling channels built into the form as it was created so that it could be produced without further assembly. Ellis is currently working on a design for KSTAR for a motor controlled mirror that can be utilized to direct the microwaves to particular areas of the heated plasma.
