Abstract
ACT2 (Active Cooling Teststand 2), a high heat flux test facility using electron beam has been upgraded from ACT facility and started the operation. 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.
