摘要

ACT2(主动冷却试验台2)是一个利用电子束的高热流密度测试设备,已由ACT设备升级并开始运行。一种新的电子枪可以在主动冷却的样品上实现稳态和瞬态热负荷。ACT2可以实现大负载面积,稳态反应堆相关热流密度(~ 20 MW/m2)高达200 × 200 mm2,并可以模拟短脉冲长度(~ 100 μs)的边缘局域模式。用石墨探针获得了约9 mm的光束轮廓。热通量是通过水热法和通过样品的电流测量得到的。

ACT2: a High Heat Flux Test Facility using Electron Beam for Fusion Application
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.
