(color online) Toroidal and poloidal cross section of EAST showing relevant diagnostics of experiments and divertor gas puff locations. AXUV: absolute extreme ultraviolet bolometer arrays; U(L)I: upper (lower) inboard divertor; U(L)O: upper (lower) outboard divertor; U(L)D: upper (lower) divertor dome; GP: gas puff inlet; IM: inner midplane; TMS: Thomson scattering; IRC: infrared camera; EUV: extreme ultraviolet spectrometer; Div-W: divertor tungsten spectroscopy.
