• Integratedtesting during EAST long pulse experiments
• Exploreuseful experience and technology for CFETR divertor
High Heat flux capacity：
Transient state（15s ON/15s OFF，≥1 cycle）-20MW/m2;
Inlet/ Outlet Dimeter(mm) -D26/d24
There are 48 modules, supporting basesand cooling pipes for the divertor system. Eachmodule contains 4 targets (2 inner vertical targets and 2 outlet verticaltargets) and 2 domes. Supporting bases include inner rings, middle bases andouter bases. cooling pipes consists of 8 inlet and outlet pipes (D70mm). EachIVT contains 3 tungsten mono-blocks and 2 End boxes. Each OVT contains 8tungsten mono-blocks and 3 End boxes. End boxes and Domes are flat plates withtungsten sheets on the plasma facing surface.
