A new design of launcher mirror for EAST electron cyclotron resonance heating system

A New Efficient Mirror Cooling for the Transmission Line of Fusion Reactor ECH Systems Based on Triply Periodic Minimal Surfaces

“…Typically, the cooling is achieved through cooling channels (following an S-shaped trajectory in the case of the launcher mirrors in EAST [16] and KSTAR [17] or a spiral trajectory in W7-X [18] and in some launcher mirrors for ITER [19], [20], [21], while others rely on serpentine cooling [22], [23]). More recently, new designs have been introduced, as in [24] for instance, where the heat sink is based on cylindrical pins around which the coolant is free to move without any predefined channel, homogenizing the temperature of the mirror. Moreover, the use of additive manufacturing (AM) for the definition of innovative cooling patterns on the nonreflective side of the mirrors has been investigated in [25], showing the potentialities in terms of weight reduction.…”
