The high heat flux test facility HELCZA is entering the commissioning phase where full parameters of the facility shall be validated. HELCZA is designed for the cyclic heat loading of plasma-facing components for ITER with heat flux densities of several MW/m² and the facility itself is capable of reaching up to GW/m² scale. The heat flux is assured by an 800 kW electron beam gun emitting electrons at 55 kV acceleration voltage.
The main validated parameters are not only the maximum power of electron beam but the whole cooling system which enables to set the inlet cooling water temperature between 25 °C and 320 °C in an adjustable water pressure range up to PWR conditions, i.e. 15 MPa. The validated flow rate in the whole temperature and pressure range is adjustable up to 40 m³/h. The sample movement is assured by three types of sample holders: a) for first wall panels, b) for in-vertical target divertor and c) for flat dummy samples and small-scale samples. Besides that there is an external electromagnetic system installed enabling to change the electron beam path to ensure the required angle of incidence on the sample’s surface. All the above mentioned systems have to undergo full validation during commissioning within 2016.
The work leading to this publication has been funded partially by Fusion for Energy under the Contract F4E-OPE-319 and MŠMT. The opinions expressed are those of the CVR‘s only and do not represent Fusion for Energy's official position.
