Performance of the Small-Scale Divertor Mock-Up

Caption

(a) Small-scale divertor mock-up fabricated by W/BNi-6/GlidCop® brazing. (b) Schematic view of the cross-section of the small-scale divertor mock-up. (c) Temperature of the small-scale divertor mock-up during a steady state heat loading. Point A and B correspond to the position A and B in (b), respectively. The highest temperature under 15 MW/m2 is ~650?C in the W plate. This temperature is quite acceptable for this mock-up from the viewpoint of structural reliability. After the 15 MW/m2 heat loading, the mock-up did not show any sign of a visible destruction.
