A new electron gun enables the steady state and transient heat load on actively cooled samples. ACT2 can achieve large loaded area with steady state reactor relevant heat flux (∼ 20 MW/m2) up to 200 × 200 mm2 and simulation of edge localized modes with short pulse length (∼ 100 μs). Beam profile was obtained about 9 mm with graphite probes. The heat flux is obtained by water calorimetry and measurement of the current through the samples.}, title = {ACT2: a High Heat Flux Test Facility Using Electron Beam for Fusion Application}, volume = {11}, year = {2016} }
